Had a tripple by-pass and weighed 186 in hospital-gained to 210 pounds now-it has been only 11 months. Why have i gained all this weight-i stopped all presecription drugs after 8 months since operation and am now on herbals such as cod liver oil. The doctors look at me as tho im crazy. I need a dururetic and a weight loss pill and something to calm my ulcer. I can stop eating entirely and lose absolutely no weight-Why.?
