      One nice thing about a watch for readings is that, while it is normally redundant, you can be separated from your phone. For example, when you are in water.

      I selected “other” because my preference (smart watch, mobile phone, or pump screen) depends on circumstances. Watch for a quick and discrete view; pump if I’m preparing for a profile or activity adjustment or bolus, mobile phone if just a food bolus.

      I’m curious about the reasoning behind using a dedicated reader. Could someone please enlighten me?

      For Minimed, the dedicated reader is the pump.

      How comfortable are you, on a scale of 1–5, with artificial intelligence (AI) being integrated into your diabetes technology?
      Sorry. I'm not sold on AI. I don't trust the people making it. There are too many reasons it could go wrong and be disasterous (just read the above comments). I'm not opposed to computers helping with things such as Control IQ, but when the computer starts doing the thinking, I think we've crossed the line. An aside: I've listened to AI music, and I think it sounds impersonal. It lacks a humanness. I don't find it pleasant to listen to. I've heard horror stories about AI being used by the military, with the end result being nuclear holocaust. I am a hard NO to AI. I gave it a "5".

      I believe that AI may very well become a great tool - but at this time it still makes too many errors for me to be confident in it.

      Here's my concern. I've used AI when meeting new clients to take notes of my meetings while I'm talking with the client. Ostensibly, this frees me up from having to jot down notes while talking - allowing me to give my full attention to the conversation. (Very good benefit of AI) Then, when reviewing the notes, AI literally fabricated scenarios that weren't discussed (AI Hallucinations are a very bad side effect). Not knowing when AI will fabricate a fact pattern gives me great concern that AI will fabricate a glucose reading and then act on that hallucination. AI has great potential, but it's not ready yet.

      "Slightly," I think, maybe. Insurance companies change their policies, constantly. Prescription coverage changes every time I look at it. Medicare is a huge question mark. Honestly, Health insurance has become a big money making business, for them. I get different answers every time I call, depending upon whom I am talking with. I say it's time for socialized medicine.

      Roughly half my lows are caused by my auto correct system now. I expect AI hallucinations to make it worse. I have enough hallucinations when I'm low and need non-hallucinatory help. We all need more info on this subject to make better decisions. As my favorite 80's AI robot (Johnny 5) said, "Need input."

      I'm not comfortable for many reasons: 1) AI hasn't proven respects boundaries, quite the opposite, too many reports of AI tend to view its responsibilities and decisions as NOT mine; 2) the companies behind AI systems do likewise in not respecting my data as mine and jumble it in with their own; 3) AI systems haven't proven themselves as reliable parties regarding data and actions. There are many more; AI systems have a long way to go before I entrust one with dosing strategies while I'm awake, let alone while I'm asleep!

      I’ve done a large 2 week focus group through Syracuse University on AI. I’ve also been watching shows on European news about AI and medical issues. AI still has too many glitches when it comes to medical issues.

T1DX-QI is a remarkable resource for centers that are using continuous process improvement to improve the quality of care for people living with diabetes.”  “Diabetes centers working with T1DX –QI have done amazing work using QI methodology to make care accessible and equitable for all people with diabetes,” she said. “It’s inspiring to be a part of a collaborative in which centers have been creative and thoughtful with initiatives to address individual and systemic challenges to care, improving clinical outcomes as well as the patient experience."  Looking ahead, Dr. Sherr highlighted the opportunity to build on the existing strong foundation. “I’m very excited to be working as a Medical Advisor for T1D Exchange,” she said. “It’s a privilege to help shape what comes next for a group that’s already doing such impactful work.”  “Sharing what’s happening in clinical practice, benchmarking across centers, and understanding outcomes is how we figure out what’s working, what’s not, and where we go next,” she said.      The future of T1D care   With this team’s vision and expertise, T1D Exchange is positioned to accelerate progress in T1D care — bridging research and real-world practice to drive meaningful, measurable impact.  Together, we look forward to advancing innovation and improving outcomes for everyone affected by type 1 diabetes.   "

      One of many things cgm use has taught the medical community and patients too is that there are many things that raise blood glucose that are not carbohydrate. Caffeine causes the liver to make more glucose. Effects vary w how much and individual sensitivities. I drink 2 cups of black coffee and see a 30 point rise over the next hr. You can bolus as a carb equivalent. I do as 7 grams of carbs.

      My coffee in the morning will many times raise my blood glucose. And other times, not at all. With everything else the same. Very frustrating. I just watch and take a correction if needed.

      The caffeine? No. The flavored creamer? A lot!! Those 5g carb per tablespoon sized flavors WAY increase my BG. More than anything else for me. I use a bar tender jigger to measure. 10g of carbs in 2 tablespoons of coffee cream requires 2 units of insulin for me. It’s really nuts how much of a spike I get from flavored creamer.

        As like Robert, drinking black coffee I have no noticeable rise in BG. Having coffee creamer I can spike, so I have to dose like I’m having a meal.

      Caffeine doesn’t affect my BG nearly as much as just getting out of bed does. If I get out of bed with a BG around 100, within 10 minutes of getting out of bed, my BG will usually be over 120, and if I don’t take correction Bolus doses, it seems like my BG will just continue rising throughout the day unless corrected with more insulin.

        If I stay in bed, no matter how long into the day, my BG will continue to slowly decrease until I get up and start getting dresses, at which time, whether in the morning hours or late into the afternoon, evening, or night, as soon as I get out of bed and get dressed, my BG will start rising without me eating or drinking anything.

        I’ve heard this phenomenon of BG rising after getting out of bed called “feet on the floor” on the Juicebox podcast. It happens to me too….I always figured it’s stress hormones kicking in.

      Coffee always raises my bg, so I bolus for 2-3 grams of carb (depends on size of cup) as CIQ on my pump can’t keep up with it.

      I live for strong, black coffee. I drink it by the potful, not the cup since the age of 14.

      Liver, enzymes, hormones – they’ve all worked it out for over half a century.

      I don’t know what the medical / psychiatric definition of addiction is. But I think I’d rather have coffee than air or water. 😵

      I haven’t noticed any impact. I start and end my day with coffee and I/2 and 1/2. For the past three plus years I’ve had to limit my coffee drinking to 16 oz or less because of chronic kidney disease restrictions. Before the CKD dx my daily caffeinated coffee/tea/Diet Coke amounts were much higher.

      It’s not the caffeine, it’s the milk. Milk carbs are sugar carbs, read the label. It’s also your liver. Everyone has an increase in blood glucose in the morning. It’s your body preparing itself to wake up.

      I’m shocked that some T1D’s can drink caffeine w/o a BG spike. But I’m caffeine-sensitive: if I drink coffee after 12 noon I can’t sleep until early the next day. I can drink tea until about 2pm, but I have to be careful with coffee. I don’t drink caffeinated soda, so I don’t know if it raises my BG or not.

      For years, I’ve not had any noticeable effect on my blood sugars from coffee. In the last year or so, I started to get a small spike from coffee in the morning, but I don’t notice it when I am drinking diet soft drinks or anything.

      When I was on the Medtronic G3 sensor it showed more of a spike than the Dex G6 or G7. With the G6 and now with the G7 it bums up just a little. I also like to savor my first cup while waking up and watching the morning news. spreading it out over an hour or so helps…

      I never know caffeine raised my glucose until I started wearing a CGM. I then changed my morning coffee to half caf/half decaf & raised bolus insulin dose by 1 unit, which works wonderfully.
