Toprol-XL and one a day

Hi,
I've been reading up on Toporal XL and read your posts, I too was put on med. about a year ago. They did all sorts of heart test and found nothing but an extra beat? I don't like taking medication unneccesaryly and after a few months stopped taking it. I slowly weaned mysefl off by streching the days, from one a day to every other day to every third day....I have no other health issues and I"m thinking if this is for heart and blood pressure , why am I taking it? .Not sure if I'm doing the right thing, but I'm afraid to get addicted to med. that I really don't need. I had a good Dr. for 30 yrs. and he retired. So I don't have much faith in a new Dr. Does he just want to run up my bill? Or do I need this? Test had run into the thousands, thank God I have insurance... So far I've been feeling fine. Sometimes I feel alittle dizzy. But the scarist thing was that I had passed out one day while working outside. Don't know if it was from the medication or heat stroke. I wasn't out to long and had plenty to drink, but then I hadn't ate yet...
