Hey everyone, I've been T1D for just over a year and until now I think I've managed it well. Suddenly this week, I can't get "low". I've gone from always being in range to having 12+ mmol 4 hours after almost every meal, even when I take corrections for the previous high. I've even raised my background insulin by 1 unit and still I'm getting highs. I'd usually go from 5mmol to e.g. 5.5mmol etc using 6 units and now suddenly I'm going from 5 to 11 using 6 units, and then when correcting I'm still going to 12s! Any advice? I don't feel ill or anything, it's REALLY annoying me right now. This literally started one time and has continued since, not even a gradual increase of the problem.
