I have been taking quinapril 40 mg, ziac 10/6.25 mg and norvaxc2.5 mg for four years..Ran out of generic Norvasc and generac ziac about 10 days bfore doctor re-prescribed. Added both back into my system (along with Quinnapril) three days ago. Acording to roommate, I began adting strange today -- unsteady on my feet, wouldn't answer questions, made no sense when talked, finally sat in my chair wnd sent to sleep (which I never do). Norvasc pill looks diferent. It is now a round pill from Ascend. Would any of these be causing my problems??. BP is now 85/53 with 60 pulse. Any suggestions
