Oh that is horrible! Reading stuff like that scares the crap out of me... I am both Immuran and Humira too. I have been on both drugs since Spring and Immuran over a year. I am feeling so off these days - I am worried that the drugs are really affecting me! My Crohn's symptoms are gone but the drug side effects are terrible.
Honestly, I'm thinking the same as you. Get off all this ridiculous medication and go see a naturopath. I don't smoke, drink, or do drugs but my problem is that I am addicted to food. I have changed my diet significantly but I can't imagine completely giving up chocolate or french fries for the rest of my life.
In response to your question, I would not go back on Immuran if it were me. I really am starting to believe that natural healing is the way to go. These drugs just seem to make one it all worse.
Sending blessings and healing your way....
