5 units Lantus at breakfast, and blood sugar 148 4 hours after dinner. I've been raising the Lantus to try to help with daily ratios rising but thinking he may have too much. ( I raise it and it helps for 3-4 days then the ratios regress again). Although the Lantus is AM he seems to always be most sensitive around midnight-1:00 am. The other alternative was that morning Lantus was weakening after midnight, but if his honeymoon could still get him from 148 4 hours after dinner bolus to 70s at midnight I doubt it would not be able to hold against dwindling basal. Rise from 1:00 am to 5:30 am. 5:30 am fingerstick was 145. Have not seen big early am rises like that before so does it look like Somogyi, and if so maybe its too much basal at night, or too much night time sensitivity. He doesn't trend down during the day though outside of meal bolus. Flat 5 hours after lunch or dinner. Thanks. I am really trying to figure out this rising bolus need, whether he needs more basal or if low stretches at night are the problem. We have not had sub 60 fingersticks at night, but sometimes 65s and occasionally several hours (3-5) between 70-80 on cgm, checked every 2 hrs by fingerstick. Edit: also does that look like another one at 9:00 pm? He was dropping 4+ hours after dinner and fingerstick read 81-gave carbs, just 7 grams. CGM tracked down to 60 but he was 78 30 minutes after carbs, then shot up to 160 (confirmed) so that's 80 points from 7 grams of carbs which is not typical, but maybe if coming from a true 60. Edit: the drop at 6:00 was a half unit correction at 5:30 am as he was 148 and trending up and I wanted to try to have that started on by breakfast. He came down so fast though (90 by 7:15) that I had him eat breakfast at bolus time and he still dropped fast, though fingerstick was 72 at the bottom.
