Hi there, so sorry you are having a tough time. The recovery takes time. 8 weeks is pretty fresh still, at least I think so. I do not think you should have a fever and would ask for further investigation to confirm nothing is going on.
I had lots of nausea with 1 huge vomiting exp, it was awful. I really feel for you. It made it scary to eat. I took food super slow after the 'room' spray down. I swear i thought i was going to burst and the nurse brought me a tiny little thing to throw up in. For crying out loud, I don't know whats wrong with some people. Anyways, i ate homemade chicken soup with carrots, celery and noodles for 2 weeks after getting home. Then added applesauce, and other soft foods real slow. It is a adjustment for sure. What have you been trying to eat? Are you able to walk around OK? It can help the guts keep moving. Be sure to be drinking fluids like water and low sugar non carb stuff.
Stay on top of it, remember you are NOT bothering your Dr. ~ Tell them if you feel bad and ask for help.
Take care.
