@Roberta,
As you know, I've had big effects from the blood pressure pills, whapping my forehead big time with a following 5 day hospital visit. The cardiologist (see him again late June, the gruff one that we enjoyed talking the next visit) put me on a med that is screamingly horrendous if you read the brochure, but seems to work with people like me who can possibly collapse with low blood pressure with even very low dose lisinopril. I had that happen three times over about five years, the dosage going down the first two, and the third one, the hospital visit.
The brochure warnings for the new one aren't helpful, all about sending pressure too high. It took me months of watching my pressure three times a day to establish clearly that what happens with it is that if your pressure is too low it will kick up, and high, kick down - it balances. Cardiologist relieved me of that and said, essentially, take these twice a day, 10 to 12 hours apart, and only chart every couple of days, live a normal life.
I chart, not the pressure except once in a while, but the times, to make sure I take the damned thing.
I've missed a few times (pills in my purse, a clue, they should be in the fridge, these need to be lower than 70 degrees), and all fine.
