Toprol-XL and loose weight

Shortness of breath, abnormally excessive sweating, unable to loose weight, extremely tired after doing a simple task (must take break). Felt much better after being off Toprol XL.

I have been taking toprol xl for approximately 9 mos. It was givien to me for rapid heart beat. My dosage has been doubled twice so that I am on 50 mg. I hate this medicine. I still have some rapid heart beat, I wake up every two hours at night, my legs hurt, and I have gained 20 lbs. I also wonder if it is this medicine that makes me sweat profusely. When I am doing yard work, or anything else in the summer heat, the water just pours off of me. I have never been a heavy sweater and I am out of doors all of the time. I want to get off of this stuff. Can I wean myself off by lowering the dosage a week at a time?

I started taking it (50mg) about a 6 weeks ago for an irregular heart beat. I'm also on Vitorin and Lisinopryl (high cholesterol and high blood pressure). I'm pretty sure the IHB and blood pressure issues stemmed from too much caffene intake. I've since stopped that, but now I feel tired a lot (fall asleep almost any time I find a couch or comfortable chair), not as interested in sex (could be other reasons for that) and slow weight gain (about 5 lbs so far, but I've been working to loose weight, not gain). I plan to speak with the doctor and see if I can be taken off now that I've stopped the caffene.
