See, I am very different on this food front. I never really "need" to eat. If anything, I think before i became symptomatic, i was more likely to get hunger pains, and really enjoy eating. Now I eat more so because i know i need to keep my weight up for health, AND because some of the drugs/suppliments I take are required to be taken with food.
The flagyl also makes me feel a little nauseated, which makes food less appealing.
