I think I am definitely going to have to come off the Azathioprine. On 150mg a day, if I split the dose I feel sick all day, if I take it all in one go at any time of day I am very sick within just a few hours. 100mg at night seems ok. I have an appointment with my GI next week but I wondered what the next step might be? Does 6MP have less side effects or is another approach more likely to be successful?
