Losing weight

I'm forever complaining about my weight and trying to find new ways to lose it. I've had enough and have though long and hard about what to do. I just want to be thin when it comes to my 10 year reunion next year. Something to show that I've done something with myself since high school. Well I have thought about using Leptitrex but then thought that maybe I should try and lose weight the healthy way, watching what I eat.
