I am with you on this!
From reading these forums I honestly thought that the surgery would 1) not hurt that badly 2) would decrease my cravings.
NOPE. WRONG.
First of all, I woke up from surgery and immediately started dry heaving because I was in so much pain. I had to beg my nurse to find my doctor and get me stronger meds STAT. Even after I got those, it was still 2 weeks of intense pain, a week of moderate pain, then a week of minimal pain. At 5 weeks out I can now say that I don't have any pain. But, having said that, I still feel very weak (probably because I don't eat that many calories).
In terms of cravings it has been quite a journey. Immediately after surgery and for the first 4 weeks I was experiencing intense cravings. I was wanting things that I could not have- I managed to buckle down and power through. Now that I am no longer on all liquids or pureed, I have a chance to eat some of the normal food that I have been craving and I am trying to get most of my nutrients through food. Finally, with the transition to soft foods my cravings have disappeared. I am not sure why! I think it is because every meal is now a battle (I take a few bites and no longer want to eat) and occasionally (and sometimes inexplicably) feel bad afterwards. Eating is no longer fun for me and my body/mind is starting to notice. That was not an immediate change but has been a gradual pavlovian one.
My point is that even though you had cravings right after the surgery it could change. Also, people who have not had surgery should set their expectations correctly. I do not regret anything- pain is temporary and food does not HAVE to be fun. But, I wish that my expectations had been set correctly.
