Hello, Iím currently on what I think is a high does of morphine sulphate to help control pain I get due to Crohnís disease. Iím on 1000mg twice a day. I just wanted to know if itís an abnormally high dose? And Iíd also like to know what the long term side effects are? I'd really appreciate any help as the guidance from my own doctors is little to none. Kindest regards, A.W.
