Quit smoking in 2004, gained a ton, ready to quit this cycle!

All my adult life, my weight was around 110 top. I'm short and small-boned and could eat and drink anything I wanted. I never exercised. I had a couple of babies, gained weight, then lost it within six weeks. Then, after 35 years of smoking, I quit. Bam! Within two months I gained nearly 30 pounds. I was gradually working it off, when a tragedy struck and I had to move. Stopped exercising and reached 169 lbs. six months ago. Yikes! Joined the Y, and it was up and down until I finally got below 160. That motivated me to join a group Personal Trainer program at the Y, which introduced me to this site. I had joined a couple of weight-loss sites, but quit after a few weeks because they simply weren't easy to navigate. I love, love, love MyFitnessPal! Coupled with the six-week personal trainer program and my own incentive from seeing my weight go below 160 for the first time in nearly four years should have me zooming!
