I'm encroaching on my senior year in college, and between senior year of highschool and the end of 2007, I had gone from 180 to 260, I was miserable with myself, as was my gf. I had high-bp and was incredibly out of shape, so I started eating (and drinking) healthy, and getting 30 minutes of exercise a day, and now I'm back down to 180 after 6 months of hard work, but it's so worth it! I'm never going to let myself get back up there again, I like my current lifestyle so much better!

and I've even lost about 10 pounds since that last picture. I've determined that fast food is the devil :P
