So it's day 3 of my pre OP diet. The first two days were crazy. I was grumpy, super tired, and hungry. This morning I had energy and surprisingly wasn't hungry. I'm just wondering how the next 11 days went for everyone? My surgery date in October 29th. I'm super excited but still nervous. I'm also having my gastric band taking out when they do the gastric bypass. Anyone else have this revision from band to rny? How bad is the post OP pain and on average how long were you in the Hospital?
