43/male...been taking Toprol XL for a year, started on 50mg, now a 100mg, makes me want to sleep all day, nothing but gastric problems, blood in stools constantly, burning of the rectum. depression, just tiredness & lack of energy all the time, most of all high liver enzymes !! Has anyone had elevated liver enzymes?? Taking only 50mg a day trying to get off this junk.
