I agree with all the above! (get Protein in, it is an overproduction of acid and it will take your body months to reduce the levels being produced, it is head hunger, etc.)
I am 10 days post op. I am getting the "hungry" rumblings A LOT and want to go inhale the kitchen with every noise! BUT... I have to stop and ask myself - is it acid, or hunger? The real, physical (correct) answer is acid. The mental (wrong) answer from years and years of bad habits is hunger.
So, I don't deny myself... BABY STEPS! BE NICE TO YOURSELF!
Sooooo, if it gets really bad and I start obsessing about it, I get a tiny tea cup of soup or diet hot chocolate and I am FULL before 5 sips is up. I then walk away. I have proven to myself I wasn't really hungry... I just thought I was. I throw it away because the LAST thing I want to do after going through three days of hell in the hospital and putting my family through everything I have is to stretch this new stomach back out and end up where I started.
Another tip - if I don't want to/ can't get something warm to sip on when I feel like I need to eat, I have been taking Gas-X when the rumblings start and it seems to REALLY help.
HANG IN THERE!!! It will get better!
