Dear Valentine... I had my surgery Oct 28, 2015 and a lot of things still make me nauseous. The big theme here is time! You only had your surgery less than 3 weeks ago! I have lost 81 lbs, and went through the same things. But now I would go through it all again. Stick to the diet they gave you after surgery, very small amounts, do not try stuff you are not supposed to yet. As for liquids, never right before or after meals, and SIP, SIP, SIP! Always take very small sips, and never ever use a straw! It will get BETTER! Do not freakout and don't ever give up. Good luck!
