      How many unopened, unexpired insulin pens or vials do you have?
      I actually don't care, consequently I don't know either. When I was diagnosed I often didn't have the $18 for a vial of Humulin and used expired insulin others wouldn't. I tracked everything. The math didn't change, old or new. How many do I have total? More than I need and enough to share through my endo's office.

      I am working through the end of my 90 day supply of Insulin. It is time to order another batch. Usually 6 vials.

      Funny you should ask right now. I had to personally buy my first-ever vial in 25 years. Thanks Medicare for all the obstacles you place in the way. Am I grateful for Medicare? Yes, I guess, but I paid in all my life and I’m still paying. But Walgreens can never get the preauth right. They don’t send it to my doc or they send the wrong form. So I had the bright idea to change pharmacy’s, Publix. I went and had a convo with them, explaining I’m on a pump, I mentioned part B, the preauth. No problem. Have your doc send the script. That’s a whole other story. Then I get a call from Publix. We don’t do part B. Wow, wish you had told me. OK, I’m just going back to Walgreens. Except Medicare won’t allow refills without doctor script. So they called my doctor and my doc declined it because they had already approved it for Publix. Now I had sent an email explaining all of this to doc. I called my doc but they don’t answer their phones. Left a detailed message but have no idea whether they got anything. So I asked Walgreens if I could buy a vial. Nope, no script from doc. So I went to Publix, explained it all and they sold me a vial for $29. It was worth it but so frustrating because I can’t get my hands on a script anymore and take it where I dam-well please. Sorry for long post. I’m angry.

      Oh sometimes I miss the old days of not needing an Rx for insulin in any state. Needles and were restricted due to illegal drug users, but then came disscsions about drug abusers sharing dirty needles. I'm not sure where that ended. Anyway it's extremely abusive for politics and insurance companies controlling diabetic supplies. The disease is a big enough burden.

      Novo has an uninsured discount for their unbranded “insulin degludec.” I pay $35 for 3 boxes of pens (90day supply). That breaks down to less than $12 per month.

      Medicare is basically not covering Tresiba in 2026 :( so I've been busy stockpiling pens. I have enough Tresiba pens in the fridge to get me through '26 without having to buy any.

      I seldom have any questions other than RX refill request which I submit through the patient portal. If I do have treatment questions, I typically do my own research, and if not satisfied with what I find out, I submit a question in the portal.

      Unopened yes, and now even opened just in case. I am getting a new health [lan (thank goodness a much better one - with better doctors and hospitals in network!) so it's worth it. But I can't get any appt - even for a PCP until September. I've been occasionally buying out of pocket insulin, pump and CGM supplies (in my mind, hoarding is a character asset for T1D people). I need to have my enough stuff to see me through, Of course, I am hoping there''s an appt cancellation.

      I have been told many times "YOU CAN'T EAT THAT!" ONLY to frustrate them and eat it anyway and then bolus accordingly.

      I think it is a common experience for most people with T1D. People do not understand anything about it. I do not take it personally. I try to educate when appropriate.

    If you use a CGM, do you ever experience “compression lows”? These are inaccurate CGM readings that occur when there is pressure placed on the CGM transmitter and sensor. They typically look like a sudden and drastic drop on a CGM graph, and often occur when a person is lying on their sensor.

      For a long time I wasn’t sure what you all were talking about when you referred to “compression lows.” However, I recently experienced several compression lows while I was sleeping. I found that relocating my CGM from areas where my body meets the mattress appears to have resolved the problem.

      Keep my Libre (now 3) on my left arm so I try to make sure that I sleep on my right side. Don’t want the alarm going due to compression lows.

      I have never heard of that being something that happens. I will now pay attention, I will have a conversation with my endocrinologist about this.

      When I had a G6 it happened rarely. Happens more frequently with the G7. For me it’s more difficult to place on arm. Always had G6 on arm but didn’t seemed to compress like the G7. Also happens more in the beginning of sensor placement. Then not so much. Annoying

      I have a hard time finding a spot that is not my abdomen to place the sensor so I don’t get compression lows. So annoying in the middle of the night!

      I’ve had only 1 in 3 years that I can attribute to laying on the sensor in the night. I put the pump infusion set and the sensor on the same side of my body, so I’m used to sleeping 10 days on my right side and 10 days on my left side! LOL! No compression lows!

      I don’t think so. If I get a low alarm at night, I eat sugar and go back to sleep. I don’t get up and double-check with a finger stick.

      While I have experienced compression lows they have been infrequent. I have a bigger problem with loss of connection to my pump if I lay on the Dexcom transmitter

      Regularly if sensor is inserted in my abdomen or arms, but only rarely when inserted on my inner thighs.

      I said Yes, but rarely because I almost always insert my sensor rotating from one leg to the other on my inner thighs.

      I tried a sensor on my calf but in the calf, it sometimes hurt and frequently gave sensor out of range errors on my pump.

      I get them when I have my G6 on my arm, so I don’t put it there anymore. I only put it on my abdomen. So far so good.

      On the G6, I got them all the time.
      I am now on the Eversense which does not have compression lows (no matter how I sleep.) I believe this has to do with the sensor being inside the body and being “compressed all the time”, so to speak.

      I said “other”. I get inexplicable rapid drops (not instantaneous, but sloping down significantly over 3-5 5-minute test periods. I had never considered this as a possible cause. When it happens, I go and do a calibration, usually finding that my true BG level is 30 or more points higher than the indicated SG. I had never considered this as a possible cause. I’ll pay attention to that now. Thanks.

      Not too often, but when they happen, we usually have multiple alarms in a night. It’s always after a sensor change when we, of course, switch arms.

      Yes and that prevents me from putting the sensors on my arms because I sleep on my sides. Now I have the sensors on my thighs nearer the inside where I won’t sleep on them.

      Yes, but with the CGM 6 not as frequent as the CGM 5. I was thinking about what CGM to use next and after reading all the comments I’m not sure what to use, so for now sticking with the Dexcom CGM 6 because in our area there’s only 1 endocrinologist who does the Eversense and sadly it’s not my endocrinologist.

      I’m a side and stomach sleeper, so I used to get compression lows all the time in Manual Mode on the 670G and 770G pumps (Medtronic). Now I run Auto Mode and have very few compression lows.
