Hello, I've been on 50mg of Toprol XL for about two months, and have had a lot of hot flashes--I mean I just can't tolerate the heat at all! Also, if I am doing any type of work that takes any exersion, like lifting boxes (I'm preparing to move) I get so hot and sweaty! I am unable to take any other type of blood pressure medication due to having had severe allergic reactions to them, so I am stuck on the beta blockers. I also seem to have a significant decrease in my sex drive (mind wants to, but body doesn't), which is difficult because I just got married. I have also had a significant change in my weight - gained a lot, which is a bit strange for me. I am now trying to increase my exercise and also watch my diet. I am 45 years old and my blood pressure, at it's worst was like 202/120. It's down to like 140/90, so it's better... Acupuncture was helping for a while, but not enough...
