VGB versus VSG
You have to learn to drink water, water, water. When you want sweets just try to eat fruit. Sometimes I take unsweetened fruit and freeze it a bit to give it a litle zing. I even take cottage cheese and add some Equal (I actually use the Wal-Mart brand as long as it is in the blue packet) and mix with some fruit to get my sweet fix.
It is a matter of mind over stomach.
