Anyone Tried p90x? What were your results?

I am starting P90x Today... Ive gained about 40lbs and feel terrible and am ready to make a lifestyle change. I am COMMITED to getting to my goal weight. I am currently 204lbs and would love to be about 145lbs. I know that this goal is going to take a while to achieve as well with a great deal of hardwork. Have you ever Completed the program? What were your results? What kept your motivation? Did you do any other program with P90X?
