I ran out of my blood pressure med, a diuretic, a week and a half ago. I had to see my doctor to get a new prescription, which I had filled yesterday. (BTW, bp with no meds? 140/90, which seriously isn't bad.)
I took the very tiny pill last night just before going to sleep, as I've done for the past couple of years. Except that I hadn't gone without for ten days before.
I was up every 90 minutes like clockwork.
Tonight, I take it when I get home from work. And presumably things'll be back to normal in a couple more days.
