I have been feeling very smug about not getting any side effects from the AZA. I've been on 100mg a day for the past week, taking it in the morning absolutely fine. Today is day one of 150mg. I took it at 7.30am as normal and by 11.30am I was throwing up bright yellow, foul tasting liquid. I haven't been sick like that for as long as I can remember. I can only assume it is the increased Aza that I am reacting to. I am going to try 50g in the morning and 100g in the evening tomorrow and pray it doesn't happen again!
