heart attack
"9th anniversary of 5x bypass.  Blood pressure was never high.   Altace, began with 5mg in the morning, was feeling faint every time I stood up all day.  Changed to 5mg before bed, faint if I got up to pee.  Changed to 2.5 mg in the evening, OK till last night (9 years) difference was had the flu or something similar, had a high fever, night sweats, diarrhea, got up to go to the bathroom and found myself on the bedroom floor, no damage, fell into the dirty clothes basket, so the warning about excessive sweat or any loss of fluids, is a good one."
