Metoprolol
"I have been using Metoprolol for about 3 years now for high-blood pressure. Started with 50mg and now at 100mg. Before the medicines I used to have a headache from the back of my neck to the back of my head every day. Since taking it, no more headaches. Blood pressure is low too. Can't seem to lose any weight though. I think I started out at 185 lbs (still overweight), but now I'm at 192 lbs and can't seem to get below that. Am pretty gassy and have frequent diarrhea."
