Hi Sarah!
My stats aren't quite anything to be inspired by (yet) but thought I'd jump in anyway.
I'm 24, finishing up grad school & working full-time, married with 2 cats

I've been on and off the diet rollercoaster... Probably lost 100 lbs if you count that same 5-10 that kept coming and going! I managed to end up back at my high weight and recently said enough's enough! I know what got me here (eating out too often, too much ice cream, poor meal planning which leads to more eating out) and I know what will get me out (revamping my lifestyle, eating better more "natural" foods, eating out less). I'm not following a particular plan, just being sensible and occasionally counting calories to make sure I'm on track.
I don't know how much I want to lose... I'm thinking 70 lbs total. That puts me at 145, but who knows, I might be happy at 150 or 155... I'm not really attached to a number, I'm more looking for what will make me feel best.
(as you can see, I take a very relaxed approach to this weight loss thing! i've been carrying this weight around for my whole life, I figure I can't do anything to make it come off in 6 months, nor can i expect it to!)
Good luck, hope to see you around.
