Wanted to post a reply to this discussion, but it's closed for some reason. Nothing bad in the discussion that I can see -- why was it closed?
Anyway, I've noticed the same thing the last 3-4 days -- I'm experience lows 2-3 times a day following my usual routine, ratios, etc... in fact, on a pump, these things are automatic.
Prior, I rarely had lows. Yesterday, I was fighting to get up out of the sixties all day, bolusing normally. Turned my 1U/hr basal off completely for several hours (I'm T2).
We'll see how it goes today. It's rather strange.
BTW, I'm just south of Amanda in the South SF Bay area (where I work), and Santa Cruz area (where I live). 100-150 mi south of Zoe, I'm guessing.
