I have used Tumblr for awhile now for fannish stuff (tv, movies, that sort of thing) but thought setting up a weight loss blog there might be fun too. It's called I Deserve to be Healthy and you can find it here:

It's pretty empty right now but I just started it. If anyone else is on Tumblr I would love to follow you there!

No Tumblr for me - I can't quite figure it out!
