Sudden Change in Bowel Habits

For the first time since starting Remicade I find myself constipated.  I felt a little backed up on Saturday, but I attributed it to my period. Well, my period is over and I'm still struggling to poop. I don't want to wait this out, so I took some laxatives tonight in hopes it will help get me regular again. In the past, laxatives don't usually work right away, which makes me skeptical of how quickly I'll actually find relief. I've also been trying to eat less to decrease the potential backup. It's hard because my appetite is raging! I'm so hungry that only having one dinner is making my stomach growl. I desperately want to poop so that I can EAT.ALL.THE.FOOD!
