Im home and starting to feel better
Welcome home! First couple weeks are the toughest. Everything tasted weird to me too, but I ate/drank because I was supposed to. Honestly, I spent every waking minute either sipping water or "eating" my liquid proteins! At the time, it felt like I was in a time warp, but it does pass pretty quickly.
It probably hurts when you get up because of the incisions in your abdomen; that'll get better with time as well.
I don't think I got hungry until 8-10 months after my surgery; I ate because I was supposed to and because my body needed nutrition and energy. Just keep following your surgeon's instructions and you'll do fine!
Also, keep walking as much as you can - it seems to help folks feel better and speeds the healing process.
Good luck and welcome home -
