You better check with your doctor. While a tight band sounds like a recipe for great weight loss, it can also cause damage to your band and perhaps contribute to a slip or errosion. I just had a slight unfill and my doctor was thrilled that I came in. 9 I too wanted to keep my fluid) Just a tiny bit too much caused me to vomit and have horrible heartburn. Like Elcee said, you should be able to eat a variety of healty foods and still lose or maintain your weight. if your body thinks it's starving, it will hold on to every pound.
Better to be safe than sorry....you wouldn't want to lose your band for good.
Good Luck!
