This is the hardest thing I've ever done! The physical part is very challenging but the mental/emotion aspects can, at times seem overwhelming. I try to remember this thing. Feelings/emotions and thoughts are fleeting. They don't last for long. Try distracting yourself with something else. I color in color books, read, watch a movie, call someone to talk go on line. Just fine whatever you things are to get your mind off of "I must eat, I want to eat, EAT-EAT-EAT!!!!
The mental aspect of why we've all eaten ourselves in to bariatric surgery and how to overcome/deal with the new stomach/life style, etc. should be worked on so we don't return to those same habits. I hope my opinion is helpful to you.
May God bless you and keep you!
