Iam having the same problems, I got my 4th fill on the 26th of May and at first I was vomiting with every meal. It was a major shock to me because I had no problem eating whatever, whenever and however before this fill. I am now down to only vomiting 2-3 times a week. I called my doctor because not only with the vomiting I was also having severe pain when I ate too fast or didn't chew good enough. He told me that was happening(the eating too fast and not chewing good) because I was going 4-5 hours without eating anything and by the time I did sit down to eat I was too hungry and not listening to my body. He said that ideally I should be eating 6 small meals a day each no more than 200 calories. So if you figure you are awake 16-18 hours a day then you should be eating at least ever 3 hours. Since talking to him I have done this and I am having no problems and have lost 5lbs this week. Hope this helped a little but as we know all bodies are different and every doctors advice is different. GOOD LUCK!!!!!!!
