Hey Merryduck
Welcome to the forum!
I think the first thing you want to do is, take a deep breath, then decide how you want to move forward. What sort of eating plan do you want to go for?
Find others on the board that are doing the same thing... we've got Weight Watchers here, Atkins followers, South Beach Dieters, calorie counters, just to name a few.
Secondly, consider eating 6 x a day (or more if needed)
small meals and snacks. My personal experience (I realise everyone is different) is that if I have protein based meals and snacks I do not get that ravenous feeling that you are talking about.
I am a Weight Watcher myself - I love the freedom of being able to choose whatever I want, whenever I want it, I just have to be accountable. Maybe you prefer a different plan though. Check out the other groups and see what might work best for you.
In any case, I wish you the best and hope to see you around the boards!
