Fitday has been a really positive experience for me. I have been using it for almost 3 years - very religiously at first, and now sporadically. I do not track every calorie anymore, but do track my weight and check in with the forums. I also use the journal section, and have found it very useful - it really helps with figuring out what triggers mindless eating, and develop strategies for dealing with tough issues.
My journey has been tough, but so worth it! I do not follow a specific "diet" - don't believe in them - just eating mostly healthy foods and limiting (not avoiding) junk. Since reaching my goal in Spring 2011, I have been able to keep my weight within 10 pounds or so, and have no health issues at age 47.
Good luck and keep posting! Your story will inspire more people than you know.
