I could swear I need a checklist of everything that can possibly happen so I can start checking these things off. The trip to the Bostonish area went mostly okay. I didn't have any significant change in insulin requirements, but the first day we were on the island, I had to lower my basal by .05 and bolus by one g/carbs. After that, everything was normal. I anticipated how much extra insulin I needed on the plane and was right. That was great.
Now, for the weird part. The first day we were there, the place we were staying was around 90° and up. By the end of the day, the insulin in my pump had gone bad. I then had to refill it with cold insulin. I do have a pump frio, but I didn't think it would be warm enough outside to bring it. It wouldn't occur to me that I'd need to use it inside, since I can't be in that kind of heat due to another medical condition. In retrospect, we really should have rented a car and gone to a hotel. I did bring a frio for insulin, but it didn't really keep it cool enough. I did make sure to water it enough and let it breathe, so maybe it's because I used the waterproof inner bag? I'm still not sure why. When we got back, I just ended up throwing out all the insulin I took with me since our flight had been delayed and it had been hot, etc.
Despite all these precautions...the vial of insulin I opened upon our return (from my fridge) was bad. The first day, I thought it could be a million things and used 11% more insulin. The second day, I used 25% more insulin. Today, I woke up out of range for the first time in six months and was using 50% more insulin (!) when I finally went, "hey, wait a minute..." After I'd decided to return the insulin, I remembered that J. once had to return some bad insulin to the pharmacy (and we use the same one). I asked him when and he said a month and a half ago. Sure enough, that's when I picked mine up. So, I took them back to the pharmacy and got replacements. The pharmacist was quite surprised and looked grim when he said he'd have to pull everything from that lot. He didn't remember J. returning his. That got me thinking...if a whole shipment of insulin goes bad, why do so few people notice? Are most people getting it Type 2 and it doesn't make much difference? It's very noticeable to me because my TDD is so low. Do people not test very often? I wonder why that is.
