Hello, I’m currently on what I think is a high does of morphine sulphate to help control pain I get due to Crohn’s disease. I’m on 1000mg twice a day. I just wanted to know if it’s an abnormally high dose? And I’d 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.
