      Do you currently take metformin?
      Before I was correctly diagnosed the primary care physician said I must be type 2 due to my age of 36, even though I was always very thin and had rapidly lost even more weight. He prescribed metformin- I proceeded to get sicker and sicker. Finally got to an endocrinologist who tested and said I was T1D, and I was put immediately on insulin. What a game changer.

      Other I took Metformim for 3 months when I was first incorrectly diagnosed with T2. I am very sensitive to insulin and don’t need it yet.

      Do you currently take metformin?
      In the late 2010s, I began to become insulin resistant and started packing on a lot of weight. I believe using a pump facilitated this because of the abundance of insulin readily available. My doctor put me on metformin, then Jardiance, then Victoza. As a result, my insulin use went from 120-140 units per day to a minimum of 24, up to 40 depending on carb loads. I also lost 102 lbs. It may not be for everyone, but if you're starting to notice insulin resistance, it can be a good weapon to have.

      I've had T1D for 50 years. I started taking Metformin 9 months ago. I take full dose at bedtime to manage my morning glucose rise. It keeps the liver from releasing glucose. It has helped.

      I took it for four years when I was diagnosed with T2. After four years of not being able to control my bs I asked my endocrinologist if I could go on insulin and he said yes and the T2 drugs stopped.

      Have you had to switch diabetes medications in the past year due to health insurance changes?
      I hate formulary changes mid year. They should not be allowed!

      I will be possibly switching from Humalog to Novalog next year. There is NO Medicare Part D plan in my county that now covers Humalog. Complicated by the fact that I use a Humalog specific Smart Pen, it will be one more hassle in T1 world. My endo will submit a formulary exception request next year. My hoarded supply of cartridges will carry me through while waiting for the response 🤞🏻I cannot believe that this is the broken system that we have to settle for in the richest country in the world.

      My doctor switched me without telling me from Humalog to novolog and told me it was due to insurance. I’m on Medicare and I never saw anything that said that was necessary. They call me periodically to see how I’m doing and I told them I didn’t appreciate being switched without being told. I thought initially it was a mistake when I picked it up at the pharmacy but they said that’s what the doctor ordered. Then the next visit, he told me all my issues with insulin switching and preauthorization holdups was my fault basically because he says “I have the wrong insurance”. Like I’m going to NOT use Medicare. My opinion? I think I have the wrong doctor, but it’s a hassle to switch.

      NEVER accerptable or appropriate. Nobody's healthcare should ever be determined by a third party's profit margin(s) to determine what we are forced to take.

      Do you have Glucagon on hand that is not expired? If not, please share why in the comments.
      Insurance won't cover and it was several hundred dollars.

      Had to, no. But Medicare is adding coverage for FIASP in '26 so it will be "bye, bye, bye, bye, bye" to Lyumjev!

      Multiple daily injections (MDI) users: Do you use an app or other device to track your insulin dosing? Share the tools you use in the comments below!
      I use InPen and it's great. Except they aren't keeping up with iOS so you now have to unlock your phone and open the app to check IOB instead of simply looking at the home screen. You can tell when app developers aren't users, otherwise they'd know how much of a pain this is when you check 50 times a day

      Glucagon is $425 for me on Medicare. It is cheaper to get an ambulance! I have an expired one that will work if I ever need it, but I won't.

      No. During the past century I threw out many glucagon doses about 5 years after each had expired - having never used a single glucagon dose.. This century, two dose kits were disposed of and never used. At this point, in my opinion, with modern tools for accurately monitoring one's body glucose levels, AND common awareness of how one is feeling, severe low BGL can be easily avoided thus not needing "emergency' glucagon. NOTE WELL!!! what I wrote in the last sentence, does NOT apply to the very young, and some newly diagnosed who have not yet mastered insulin dosing and who have not yet been accustomed to recognizing low or quickly dropping BGL.

      For me it seems to be a function of how long it;s been since I had the injection. Another impact is how intense the exercise is. However I think this is the thinking around Blood glucose levels, and exercise. along with whaet you ate…

      I don’t know, I haven’t noticed. I have more outdoor “exercise” in the summer, by which I mean yard work. And it will make my BG go down, just like any other activity. The only outdoor exercise in the winter is shoveling snow.

      I bike to work year round, and I have not noticed any difference due to temperatures. I imagine heat and dehydration could potentially have an effect, but it’s not an issue for me on my daily ride. With all the factors affecting BG level, I hope the weather is not something else to worry about!

      Being a senior in my 70s with T1D, I don’t do well in the HOT or COLD because they both seem to cause sugar fluctuations. Now I know why seniors head south in the winter and north in the summer. We diabetics just strive to control and time in range!

      My only issue is that, during the summer, I can sometimes attribute symptoms of an oncoming hypoglycemic episode for heat stress. A quick check of my Dexcom usually resolves that.

      I notice a huge difference in the heat. My blood sugar can plummet and I need to be extra careful to not have any IOB.

      Usually exercise outdoors in moderate weather. Extremes really anytime I exercise anywhere I rely on my CGM.

      I think mine drops more in hotter weather only because I spend much more time outdoors then. I stay in a lot when it’s cold. In fact, getting ready to hand mow my 1/2 acre lawn in feels like ‘104’ degree weather here in TX.

      I exercise outdoors by walking the perimeter of the yard, adding laps over time. Live in CA, so no cold weather.

      I don’t know. I am not fond of hot weather as my body does not seem good as temperature regulation and I don’t often exercise in the heat. I can put more clothes on in the winter, but they have yet to come up with AC clothing….
      This body definitely drops when I exercise in general.

      I monitor with the CGM. Gave up on feeling an insulin reaction long ago. By the time you physically feel it you are well on your way to an insulin reaction. Hot weather tends to drop my blood sugar more quickly. What I’ve read is because your cardiovascular system is working hard to keep your cool and your vascular system expands to get that job done it absorbs your IOB faster.

      I have no idea. I hike in all weathers, 90f to 10f, and usually set a temp target starting one hour before I hike for 2 hours. Sometimes I need a snack and sometimes I do not. There are too many factors for me to tie it to the weather.

      Heat does seem to drop my BG faster when working outdoors. Working in the yard, tends to reduce my stress and so my BG drops rapidly LOL!
