First Fill Yesterday- My experience

Hi All,
I had my first fill yesterday, and my dr did it under an xray, and immediately I felt full without eating. Unfortunately later on I got a headache, because I didn't eat and eventually started to vomit. The weirdest thing was that I was "HEAVING" and nothing came up, until about the 4th heave, where very little fluid came out. It was a bit scary. Today is a bit better, and I am not eating as much, but am scheduled to go back for my 2nd fill in 3 weeks. Just a question.. Is the first fill normally where you would feel fully restricted, or does it take about 2 or 3 fills? Also, my doctor instructed me that mere walking was not enough, that I had to get on a "TREAD MILL" to maximize the weight loss. My surgery was on 1.23.07, so I guess I should get started. I did Join the gym and am scheduled to start tomorrow, at an attempt to do 3 days a week.
Any advice on starting out on the fills? I am just so anxious to see some true weight loss I don't know what to do!:help:
