Congratulations Mikey:
I am glad you are doing this, you are still very young and this will make you a lot healthier. 
I signed on Medifast a few months ago, and so far I am down 40 Lbs. and I have other 16-20 more to go, 
I already notice that the pain I had on one of my knees is almost totally gone, and my High Blood pressure is leveling 
to a more normal numbers.
Keep it going, you will make it, is within us to make it happen. 
Kudos.....  
 And of course, a very Happy New Year, and much, much healthier too.
Manuel
