i feel the same way too, ive just resently rejoined my group (5th time). i find it easier to go to class as i find it helps when someone else is keeping an eye on me. you also pick up loads of food tips.
Another reason i like going is, i find someone in the class roughly the same size as me...
i love EE, you can mix all foods together and it doesnt even feel like your on a diet, which means when you go out with friends you can choose most dishes off of the menu, with out juggling for the rest of the day.
