4 days post-op: Down 16 Pounds... not fat?

I had surgery early Monday morning. I stepped on the scale, 5 days later on Friday, also early in the morning. I went from 271 to 255.5 pounds in 5 days. That's almost 16 pounds... in 5 days. Seems like a lot, almost abnormally so.

My grandmother seems very excited for me, however, I keep telling her it's probably just my liver shrinking and all the waste leaving my body. Is it bad that I'm being pessimistic?

I've had no issues with constipation. Still gassy, but it's making it's way out pretty fast down below and I have no shoulder, side, or chest pains. Walking a few hours after surgery and walking blocks around the surgery ward every 2 hours really did help me, I think. A lot of the nurses were amazed. I didn't see many other bariatric patients walking around until late at night I saw one man walking a little bit from his room until he turned around and went back.

I remember the next day after surgery when I did the x-ray test and had to drink that nasty liquid, I ran into a young woman named Monica waiting for it, too. She looked at me and asked "What did you get?" I mentally laughed and then said the vertical sleeve, and she said she had the same. I asked her what he goal weight was and she said 140. I'm going for 150-155. We talked about gas pain, but I told her I was up and walking a few hours after surgery. I know I mentioned the VST forum and asked if she was on it, and she asked me my name, but I thought she meant my username.... obviously the drugs got to me and I gave her my username (Castiel is a name of a character from a TV show) and yeah.... so she didn't know my name until a nurse called it. probably thought I was crazy haha. I didn't see her walking around the floor at all during my stay nor could I find her room til the very very end right before she was leaving :[ I wanted to wish her good luck!

Right now, I'm seriously hungry. I'm only on clear liquids, no protein. I can't stand the taste of isopure. It's revolting! I thought it was okay before surgery, but that weird filmy after taste and the smell? no thanks. I know it's bad, but I had a half of a teaspoon of peanut butter over the course of a half hour with water swished in my mouth. I was prepared to get sick, but so far I'm okay. I feel drained of energy, and I just need some good tasting protein shakes (not until monday). These next two weeks of liquids and full liquids can't go fast enough! I'm ready for some mashed potatoes and pureed beans... maybe even with a little sour cream, and a glass of milk!

I think the hardest part is getting through this month until I can finally get to soft foods. Head hunger is killing me and I can't wait to have smaller portions of healthy good tasting stuff! I'm also paranoid I have leak already, but I guess I'll find out when I have a fever and more intense pains. I seem to be straining my stitches a lot :[
