24 years old with 35lbs to lose

I have been on this site for 2 months now. I'm 24 years old, 5'1" and my goal is to lose 35lbs. I am currently 169lbs and would like to weigh around 135lbs. In the first month on this site I lost 5lbs and was ecstatic! Then during the second month I started slacking on the weekends and I maintained my 5lb loss but I did not lose anything else. Then 1 week ago I went on vacation and gained back the 5lbs I loss. So even though I'm not a newbie, i'm technically starting from square one again. And I would love some new friends to help me along this windy and bumpy path. I figure the more support I have the easier it will be for me to NOT eat that extra cookie or slice of pizza! And hopefully some of the things I do can help to motivate you guys to continue along the right path as well! So if you have similar goals or not, are still on your journey, or already made it to your goal...I hope we can help each other out and learn from each other!
