Hi, sorry for the late response to your questions, but there are a couple ideas I haven’t seen offered.
A good CDE once proposed a “vacation” from T1D could be taken by having someone else make all the decisions, calculations, & treatments for a day - check your BG, count your carbs, and adjust insulin doses. Sounds great, but it is clearly impractical.
Someone I know stayed on a carb-free diet for awhile, and learned that his control became very stable. If your basal is pretty correct via injection or pump, you’d use little/no bolus insulin = no highs & lows & very little variability. He loved it! But it requires strong dietary discipline.
Hang in there, I hope one of the suggestions works for you!
