Aww, that sounds pretty miserable, I'm sorry you feel so icky :(
I was having trouble going when I was in remission and they had me take Miralax -and- Philipp's caplets each day and that helped. It did take about 2.5 days for me to be able to go enough to feel better, and I could not do anything other than drink liquids in the meantime. They had me keep taking both of those laxatives for 2 weeks until I was doing ok with going and eating normal amounts of food, and then I was able to start eating some fiber again and take just one or two philipp's and be ok. After a week with some fiber I didn't even need the philipp's. I hope you are able to go again and start feeling better soon, perhaps if you call your doctor again they can try another enema or give you some more of that gollity stuff since you said that helped a bit last time.
Miralax seems to be a favorite for many these days. Drink as much water as you can.
