So I lowered my basal rates (all day) by the minimum amount and ran high for two days.
So I put my basal rates back up, and lowered my I:C ratio and ISF the minimum amounts, and again ran high for two days.
So yesterday I put my settings back to where they had been. Yesterday and today I had a grand total of one high (woke up this morning at 12.0/216). Great!
This afternoon I was talking to a colleague in the hallway, walked back into my office and sat down, and suddenly felt sort of lightheaded. Zero other symptoms whatsoever. I hadn't noticed being a bit lightheaded while talking and walking, only when I finally sat down and was still. I tested at 2.6 (47 mg/dl). Ate about four glucose tablets. Twenty minutes later tested at 4.3 (77 mg/dl) but was going to teach for an hour so felt nervous, so ate two more glucose tablets.
About an hour and 20 minutes later I was on my way home and felt off, so tested at 4.3 (77 mg/dl). Even though I wasn't low, I ate a glucose tablet. Not ten minutes later I felt no better and could not believe I wasn't low, so I tested again and this time I was 3.3 (59 mg/dl). Ate three more glucose tablets.
An entire tube of glucose tablets gone over the span of an hour and a half.
I got home 45 minutes later and tested to find myself at 4.6 (83 m/gld). I'm lowering my basal rates at least for this segment of the day.
I find it crazy that minimal changes in my pump settings can make the difference between me going low multiple times per day and me running in the double digits (around 200 mg/dl) all day.
It was really hot out yesterday and today, so maybe that contributed. Also, my latest infusion set did NOT fall out or have to be held in place by tape, which is a miracle. Skin Tac arrived today which makes me so happy. Maybe my sets being "loose" constantly contributed to the highs. I'll give Skin Tac a try tomorrow night and maybe then lowered settings will work for me.
