How do you know when it is tight enough

I've had 2 fills, and each time, it feels like I am way too tight, he will put 2cc's in, and then I go to drink some water, and it makes me instantly sick, then he takes 1cc out, and instant relief. But then a week later I feel like I have no restriction what-so-ever. The last fill I had, I could drink the water, but it made a really awful gurggaling sound, and they told me if you hear that sound, you need unfilled. I'm not losing weight like I would want, mainly because I can eat, and I know I am supposed to use my portion control, but it's hard when your stomach says you need more. I want the perfect fill, but I don't know how to get to it. Maybe I should try to tough it out when the water gurgles in my throat? Any advice would be awesome.

Wasabubblebut,
Thank you sooooo much for posting that. Your my hero. I needed that in the worst way. Going for a slight unfill tomorrow. I can't even eat ice cream.

Tracy's website is just fantastic. I don't usually write anything when I post one of her links because there is simply nothing more to add. She says it all and much better than I would.
