[QUOTE="EllieM, post: 2272511, member: 372717"] Uggh. I hate hypos. I finally took the plunge and invested in a trial of a Dexcom g6 (started 3 days ago on Monday). The alarm possibly saved my life last night. So, I went to bed as per usual at 11.30pm, and took two glucose tablets with my lantus, because my bg was at 4.7, rising from low warning territory of 4.4. I also increased my lantus to 17 from 16 because all my nightly figures show a gradual rise overnight. An hour later I started to go hypo and had to give myself more and more glucose to keep my levels up (kept heading down into 2 territory). After about 50g of glucose levels finally went up to 8 at 2am, but then headed straight down again and at 4am I had another 20g of carbs to haul myself back up from high 3s to an eventual steady level of around 7.5 which finally started rising at 7am (dawn phenomena?). I am pretty insulin resistant (1 unit of insulin for 3g of carbs) so did I just accidentally take Humalog instead of lantus? If so, why the new hypo at 4am? (Or was that the tail end of the Humalog?). Could the lantus have acted as a short acting insulin instead of a long acting one? I guess I'll have to inject multiple doses of Humalog all day if that is the case, but the Dexcom will let me know. On the plus side, I used my glucometer a lot last night as my blood sugar stubbornly kept dropping, and it matches very well with the Dexcom, giving me more confidence in said device. (When I used the libre I developed an allergy and its results became completely erratic and/or random so I've spent the last couple of years fingerpricking 8-10 times a day.) It's not the first time I've done the Humalog/lantus mix up, but I really don't think I did this time, and the relentless plunge of my blood sugar was terrifying. (I am used to 1 or 2 glucotabs being enough to pull me out of a hypo). [/QUOTE]
