Hi

I've been having headaches and dizziness for just over 2 years now and after several visits to my doctor, my blood pressure has been much higher than normal. I had some tests done and my doctor mentioned something about having low red blood cells but didn't go into detail and asked me how much I normally drink which is not a lot, the most I would drink in any one week would be 2 pints of lager or 1 bottle of wine. I'm not a heavy drinker and drink doesn't help when you have depression. She has prescribed me tablets called "Lisinopril" which is an ACE inhibitor and is to widen my arteries/blood vessels to lower my blood pressure. I'm scared to take these and wonder if anyone else is on anything like this? If I start taking them, does that mean I have to continue taking them for the rest of my life? Are there alternatives? Also I don't really trust doctors, I have had several mis-diagnosis in the past. I don't want to take these tablets if it is a mistake. Though I don't doubt that my arteries have narrowed causing the high blood pressure. I'm still fairly young, can proper exercise help?
