Congrats man it feels great I bet. I ran into the same thing a year and a half ago (maybe a little longer). One day I realized how pathetic I was and made a lifestyle change. I completely changed my diet and started exercising. I have lost around 160 pounds and still losing. I'm now at 6' 3" 225 and I have no desire to ever go back to my old bad habits. People always tell me if I'll eventually quit and gain it back which might help with the motivation more.
