I have a question for you tal. What is your diet like? If you are drinking coffee that may be contributing to your loose bowels. Have you tried any rectal meds? How about probiotics?
I can't understand a GI doctor who takes off for the weekend and can't be reached. In my GI's practice there are three other doctors and you can ALWAYS get ahold of one of them, weekends, middle of night, etc. I was hospitalized in May and my GI doctor was in contact with the ER physician at 2 a.m. on a Sunday morning.
I am also on 6MP. It does take about three months along with the prednisone to kick in. I had to take prednisone for seven months this past year before reaching remission. Doc not happy about it and neither am I but it finally worked. Remicade is NOT an option for me.
