I used SBD Online when I first started the diet a couple of years ago, but I found after only a couple of weeks that I didn't really need it. The book was all I really needed. The diet is pretty simple to follow once you get used to it.
I joined SBD Online again this time around thinking there might be some updates or new information I might want access to....
There isn't really anything I didn't already know.
I'm cancelling tomorrow while I'm still in my 7 day free trial period. Now that I've found this free support forum, I don't really have a need for the other site.
My two cents...I hope they helped!
