Hi there... been there.. it takes time... and patience and persistence.

Go for bland foods that are soft and creamy. It doesn't have to be unhealthy. Try having a smoothy with protein powder and fruit. Mild foods are best to ease you into the whole thing. I still give up in frustration when eating at times. But mostly I can eat anything and enjoy it now. But it has taken a long time to get to this point (3 years)

To help your ulcer heal - be fastidious about cleaning. After you eat and drink anything, clean your mouth and rinse with the salt water/baking soda mixture and leave it.

Hugs and welcome... you will get better and the desire to eat will return as things begin to feel better. But do mind Christine and eat and drink to survive - nutrition (good nutrition) promotes healing.
