I am 44yrs old and have been on toprol xl for about 4yrs. I get short of breath every morning and I can't sleep. Sometimes my body feels like it's internally trembling especially at night. I cannot lose weight and actually gained 30 lbs since I've been on it. My hands also go numb sometimes at night. I've been reading eveyone's complaints and really believe it has to be this medication. I must get off this crap soon. Goin for a second opinion.
