I am 6 weeks post op and still have a sick feeling, no desire to eat anything. Please tell me others had this and it passes. I can't imagine being like this forever.

I didn't feel human till about 12 weeks... seriously.

My appetite came back in full force around 8-9 months an I had to learn to control it by eating low carb.

This is temporary, you will feel better in time. Take advantage of the distaste for food, use food like "medicine" - this is that time where the surgery helps you the most in letting go of the overuse of food.
