Hey, I've been on in since march. At first I had terrible nausea, it was awful. However, my dr had me start on the 200mg dose at full force instead of working up to 200mg. I think that would have helped. Also I had issues with my liver enzymes getting out of whack. It seems my magic number dose is 150mg. I've been on that for a few months now and no problems. Once in awhile i still get a bit of nausea which I can only really contribute to my azathioprine. I also am on Remicade. Between the two drugs I'm feeling much much better! Good luck! (Oh yeah, I've also had thinning hair, sunburn easier, nothing too consequential)
