Im 3 weeks post op and today im starving im hungry and feel i have to eatim making healthy choices but im really hungry is this bad. And im at a stall depressing

Keep your head up you will get over this hurdle. Could it be acid what antiacid are you taking?

Im just taking over the counter acid reducer for the past 4 days ive been barely hungry and couldnt keep somethings down today all i wanna do is eat

Head hunger is very common at this stage. Just keep drinking your Water and Protein shakes. Once you start eating real food it will go away.

Also, the 3 week stall is even more common. Nothing at all to worry about. Read the link in my sig. It will explain why and when it will end. Just be patient and hang in there.
