I too was sleeved on the 16th. The thing I can say is try to get in the fluids. I've also had a few hiccups post-op. I keep reading and forcing myself to get the goal amt of fluids and proteins in. I had the worst case of acid reflux and gas, skyrocketing blood pressures post op so what I can say is I feel scared but not yet regretful. I am starting to feel hungry. I have to put lemon juice in my water to get past all the sugar-free but still sweet alternatives for water. You will get through this but you may also consider visiting your doctor sooner.
