Frank, welcome! You're story is pretty much the same as mine--I've lived most of my life at 300 plus and plenty of it at 400 plus.
FitDay worked for me "last time", back in '01 when I got down to 184 (coincidentally, where I am now), quit using it and well, you know the story!
This time, I'm older, perhaps a little smarter and have come to realize that I'll never be able to eat "normally". I need to track what I eat and that's a small price to pay.
Anyway, I hope you stick around and contribute when you like. You're welcome to join our "100 Pounds (or more) to lose thread over in Diet Tips--sometimes it's nice to talk to people who understand what it's like to be 200 or 300 lbs overweight.
Also, you might get in on the Lose 10% of your Bodyweight by April Fools Day challenge.
If there's anything we can do to help, just say the word!
