I've heard of one other member here who had a tube in after surgery. That person (I can't remember who right now, but hopefully they'll post here soon) used the tube for feeding to bypass the wrap. It sounds as if you're still "eating" via the normal route, if I'm not misunderstanding what you're saying.
I understand the craving food part. We all go through that! Hopefully your surgeon will free up your eating rules very soon. Try to surrender to your recovery and follow its lead. You can't rush your healing...your body will heal in its own sweet time.
Hang in there! Here's a link to my recovery journal. Maybe it will give you some comfort as you can see how another person's recovery progressed. There are also some additional posts you might find interesting.
