I have used fitday off and on since October of 2002 first the online and then in March of 2004 I bought the download.
I went back and looked very carefully. The longest period I ever used it consistantly prior to now was for 5 weeks in 2002. I would use it for a week or two and stop. Usually I would run into either a bad day or a meal out that I didnt know what it was and give up. Or I would get tired of food logging and figure I could now go it on my own.
I have now used fitday everyday for 10 1/2 weeks. Through holidays and a couple binges and eating out and everything. And guess what, I am more successful than I have ever been. Hmmmmmmmm
