I've experienced this a few times with certain diets. It sucks. Eating the same stuff everyday is no joke. I would start gagging when I thought about it and would have to force the food down. Of course, I didn't have to eat that stuff to survive.
Yep, that's how it was with me too. I got to wear I just wouldn't eat anything at all because I was never hungry, or when I tried to eat I got the dry heaves. Definitely not fun, or healthy.
