THe sulfa is fine, I think, I really don't know anymore what makes me bleed and what doesn't. I don't get a rash or anything like you experienced. You are right, the clay reeked havoc on my bowels and I was bleeding huge! I won't be doing that or physllium again! I was detoxing too I think, my heels were killing me and I started to have a cold (stuffy head and headache) but that went away after a day and today I'm much better, but still have urgency and bloody stool :(
Thanks for writing.
UC since '05, now sulfasaladine (4 pills a day),I've been on Rocephin shot weekly, for Lyme's disease, that's worked amazing for my gut issues of gas, bloating and pain. I highly recommend it!
