Hi Winni
I just started Imuran. It's been 4 weeks. Asacol and Colazal made me feel worse.Cramps,gas, more blood then when I went off those drugs. I know it usually takes a while for these drugs to kick in. I feel much better in only a month. Still bleeding, but a lot less. I added Probiotics,Turmeric and Boswellia to the mix. Hope this was helpful. Faith
