I take 25 mg of hydrochlorothiazide a day, but for some reason, today wasn't thinking. I believe I may have taken it 3 times, don't ask me why, and been having some blurriness of vision, some disoriented, and now a bad headache and just don't feel right. Should I be concerned if I may have taken 75 mg in a day. Possibly may have only taken 2. I know I took more than one dose.....thanks
