Tapering off meds--so frustrated

I saw my GI last week and we agreed to stop the Flagyl and to start weaning off the entocort.  Of course, I stop the Flagly immediately, and started taking two Entocort per day instead of 3.  Now, I'm a mess.  I'm getting contraction like pain when trying to go to the bathroom.  It hurts so bad that I get chills and then break out into a full sweat.  I almost feel like I'm going to pass out.  This has happened for the last two days in a row and now I'm physically exhausted.  Today, I decided to go back on 3 Entocort to see if that will help.  I'm so frustrated!!  I just want to feel normal again.  I'm not constipated--it's a mixture like a loose stool that is coming out.  I feel like I'm giving birth though.
