Prior to the reintroduction of any solid food is the time that you will have really rapid weight loss. Popsicles are good for flavor. I ate a lot of crushed ice with Crystal Light. I did not have the gas pains but they are expected. For the long run, which you aren't thinking about right now, don't drink during meals or you will flush the food through your pouch and end up eating much more. That is a big thing. You will be really glad that you did this. The weight will come off fast as you start moving around and burning calories and taking in hardly any.
