I Am On Several Heart Meds As Well As Others

I am on several heart meds as well as others and am gaining weight even though I stay with ,y weight watchers. I am on Losartin, estrodial, amlodopine, metoclopramide, pantaprazole, levothyroxine, busiprone and metoprolol. Am tired all the time and having joint and muscle pain. I am thinking to stop taking them all and see what happens, so tired of feeling like this.
