When you say sick to your stomach, Are you vomiting? I had my first fill about 8 weeks ago and the first 5 weeks, I vomited many times. I was okay with very soft foods but I had a problem with most solids. Apparently my band was too tight and they had to withdraw 1/4 of a cc. If you are vomiting, call your doctor, too much vomiting can lead to band slippage.
Good Luck.
