And i don't know when Im full

Some people don't really have hunger after the sleeve. Others do. It also tends to make a difference how far out from surgery you are.

I had it last Friday

Oh okay, I would say it's totally normal then. When you are first sleeved, the nerves are severed during the surgery. It takes them awhile to heal and during that time most people don't experience hunger at all. Even those who think they do, are often only experiencing excess acid. Chances are you will feel hungry again after your tummy has fully healed, however it likely won't be like it was pre-op. I still get hungry, but it's a very manageable hunger now and it takes very little food to fill me up. I'm about five months out.
