I kind of understand the eating causing pain scenario but it has been many years for me, and my was from CD. At the peak of my disease, I was so afraid to put any food in my mouth that I would go all day w/o eating to avoid the major pain so that I could continue to work. Then in the evenings I would try to eat something and usually spend 1/2 of the night writhing in pain. I, too, was on Belladonna at the time but in suppository form; plus oral pain meds as well, just to get thru the day. Be sure you drink plenty of fluids....you don't want to get dehydrated on top of everything else. I also did the hard candy trick - help satisfy the craving to put "something" to eat in my mouth. As soon as I would drink or eat anything digested as a solid, even something like a smoothie, I would be in pain. I do understand eating = pain. It is a horrible thing to deal with, but just keep in mind that there is light at the end of the tunnel.
