I don't take bp meds for that exact reason- I'm on the low side naturally (so far anyhow) and every time my doctor suggests it for the kidney protective effects- I decline the invitation.
Vacuuming and floor scrubbing drops my sugar like nothing else. I do not know why, I don't even break a sweat, but my doctor always jokes that she has a very large house with a lot of floors and carpets when I mention it to her. Yesterday (must be the nice weather?) I was down in the low 60's myself after I did my tile floors.
I sometimes drop unexpectedly when I'm doing shows and on my feet for a long time without a break. I keep a couple of those of those tiny cans of Pepsi handy.
Here's what I do when I drop too low for comfort- I test, eat/drink 15 grams of fast acting carb (sweet tarts, smarties, glucose tabs, glucose gel, sugared soda, 100% orange juice), wait 15 minutes, test again- repeat until I'm back in the 80's. It usually takes 1 or 2 rounds. By the time I get like that, it's usually the glass of coke or pepsi that gets me back to normal the quickest.
Since none of my meds are known to cause lows- when this becomes too much of a regular occurrence, my doctor and I have the talk about dropping my meds back again.
good luck getting your meds regulated
