premature ventricular depolarizations
"I have PACs and PVCs mostly related to stress and anxiety. Nothing that was overly concerning. I was medicated because the feeling of the PVCs was interfering with my quality of life. Between metprolol, antidepressants and prn ativan, I gained 40lbs in 1.5  yrs.   I got more depressed.   I was exercising too. I stopped  all meds  and no change despite amping up weights and cardio/  no sugar etc.   Nothing. I stopped the metoprolol, and I drop 16 lbs in 1 1/2 months.  It also causes depression and weight gain as a side effect.  However it  is effective in treating many other conditions. I do not condone stopping medications without consulting your physician."
