question for all post-opers

Its been 2 month and 2 fills later. I just recently started losing weight. Its only been 3 pounds but Im happy with that. My question is this:

Until my second fill I could eat whatever I wanted with no porbs. After this 2nd fill....sometimes I eat a few bites and I feel it getting stuck, it hurts and IM done. Other times I eat normally. I never know what its going to be. Last night my family went out to dinner. I ate 2 bites of fish and spinach and drank a gulp of water and ....blah. I sat there for 20 minutes trying not to throw up and then it passed. I was able to eat small portions of my meal and everything was fine. I was drinking water while eating.

What is the deal? Does anyone have suggestions of how to NOT have food get stuck? I know to eat slowly ( I dont have a choice in that) and I know I cant do heavy carbs. Just wondering if anyone has found something that works for them. Its so embarrassing to having that feeling when you are out to eat.
