I have been to a couple. Each one has a different topic. The one's I have been to were on liquid calories, exercise (showed us chair exercise), and the one coming up is on Vitamins (with samples). They are nice to get a little more info to educate yourself, but also you do get to meet some people who have gone through or are going through what you are experiencing now. At my group meetings the nutritionist is also there so that if you have a few random questions, she is available.
Worst case scenerio....you don't like them and don't have to go again.
Best of luck to you!!!
