Post-op Visit Update

I saw the surgeon yesterday for my first post-op visit. I am officially down 31 lbs since my preop visit and 38 lbs down since I first saw him in October. Even more if you count from my high weight over the summer but I'll take any of those numbers. :)
So the weight loss is definitely a plus. On the negative side, I have a lot of nausea and weakness every day and I am really struggling with eating or drinking much. The Dr. gave me an Rx for Zofran which should help, although he cautioned me that he doesn't want me to get dependent on it. I'm primarily concerned about getting dehydrated so I'm forcing the fluids more than food but it's really hard when just the thought of taking one more sip of anything makes me want to vomit. He also cleared me to start pureed foods so I have a wider variety of foods to choose from.
I took some sips of diet ginger ale yesterday and it was really helpful. I don't want to be drinking much (or any) diet soda at this point, but if it's something I can get down without feeling more sick, then I'll take it. Lemonade Crystal Light is also something I'm doing better with. Liquids that are very cold or very hot seem to sit the best.
Today so far I got down half a protein coffee and some crystal light. For food, I made some deviled eggs and ate 2 (both halves of a single egg)  over about 2 hours time. Hopefully I'll be able to get a few more things to eat before the day is out.
I still haven't learned the point in which I  need to stop eating before I get so full I want to vomit. It doesn't take much, i.e. 2 bites go down fine, then the third seems to sit in my throat for an hour. I would probably feel better if I upchucked that last bite but I don't want to start any bad habits. Plus I really do need the nutrition.
Pain-wise, the discomfort is getting better but I still have a lot of sharp, stabby pain at the incision line, especially while sitting up, even if I'm partially reclined. It feels better to stretch out fully and I can sleep on my stomach without much issue. However, that is dramatically getting better and I have moments where I realize my incision didn't hurt for a few hours.
Overall, I think I'm doing about as well as can be expected for 2.5 weeks after surgery. I do sense things getting better so I'm trying not to get discouraged.
