Since starting levoxly i have been to the emergency room twice for heart palpitations and chest pains, my doctor says everything is in range but i lower the medication as i lose weight and the lab results are the same with and as i lower it the palipitations stop, my doctor tells me this isn't the medication because i am in "normal range" but i know it is, they are simple cause and effect. when i get palpitations as i lose weight, i lower it and they stop. I am in law school, i have had a complete inability to concentrate and flunked out of my first year, i'm not sleeping and eating is hard because i am so naseus, i don't think that our doctors realize what this is doing to us!
