Thanks, Freddd. What it is, I get potassium almost completely from foods, and I eat most of it between 2-7pm, mainly 4-6:30. And my theoretically-potassium-related symptoms are leg pains of various sorts, that often wake me up around 6 am (though anytime 3-7, and once at 2 when it was really bad -- the night that led me to start the 'Ow!' thread). So that's in the ballpark of 14 hours, but could also be accounted for by being still and sleeping for 6 hours or so previous. As for insulin, I do not feel hungry when my leg pain wakes me up, and I have to force myself to eat a banana if I conclude I need one. I do that plus take a potassium pill -- the pill alone hurts my stomach. Normally I don't eat until fruit at noon, and no carbs/protein till 4ish. I couldn't tell you if I have other LSB symptoms like spaciness when my legs wake me up, because sleepy . I do not feel grouchy, though.
