Welcome to posting!
I'm really glad you decided to join and stop lurking ^_^ Congratulations on the changes you've made so far! I think it's excellent to want to get portion sizes under control and add in regular activity of any kind.
There's a WW section under Diet Central, and a 30-something's area... and well you've been lurking around so you know!
Join in on any or all sections you'd like.
You can do this!
