I have had so many surgeries on my intestines from Crohn's, holes in my intestines and Colon Cancer from the darn Crohn's, every time I tried to eat again it was slow going and sometimes i didn't even feel like it. I would start with liquids like you and nice warm tea, then creamy things like ice cream puddings, yogurts (yogurt is very important for people like us). Then simple things like crackers, toast "just a little at a time" and drink boost its very good for you and it tastes soooo much better then ensure. You have to remember your body just went through a very traumatic experience it needs time
Try not to rush back into work if you don't have too,your customers will have to understand...You have to come first! Please don't make the same mistakes i did
I hope you feel better soon, please keep in touch.
