How to eat with no appetite?

I have IBS. With severe diet restrictions I manage to only be in pain only about 25% of the time. But over the last 15 years it’s gotten so that I really resent food. If Soylent or something like it were an option for me (it isn’t, and power shakes generally aren’t, because of the ingredients) I would happily never eat real food again. And when I’m in pain for days on end, like this past week, my appetite completely goes away and eating actually feels kind of disgusting. I’m already only like 100 lbs soaking wet, so if I don’t eat enough I get pretty hypoglycemic – really shaky and start feeling very anxious and eventually frantic.

I know many of my old Fluther pals also have digestive issues and/or are cancer survivors. What are or were your strategies for eating, when food is just awful?
