You are NOT alone! I was sleeved just over a week ago. I had a similar pain the day after too. Although I had water and a little bit of gelatin. By Day 2, I felt 100% better and by day 4 & 5 I was GREAT....now I'm at day 10, and I just told my doc I don't even feel like I had anything done! Of course the liquid diet is a frequent reminder...but I feel FANTASTIC! Best wishes....it will get progressively better but if the pain persists, talk to your doc for an upper GI to look for leaks.
