Hi Dizzi v and
I am 23 yr. old wife myself, I am not in school, but I do work full time at a marketing firm!
I have considerably more weight to lose than you, but I've already been walking. I try to walk 4-6 times per week, for at least 2 miles.
If you'd like to email or IM back and forth to help keep eachother on track, I'd be more than happy to exchange information w/ you. Just send me a PM....
Anyway, welcome to the boards again, and good luck w/ your weight loss. You've come to the right place for support and encouragement.
Chantal
