hey girls i'm extremely interested in buying the p90x dvds - i just had a few questions about it... i need to loose 30lbs
and i'm willing to work really hard - does it help with weight loss - almost all my weight in my belly .. yay - u know how that feels

typically how long does it take to come in the mail?
what should i expect?
should i follow the diet that comes with it? or should i follow another diet like the insulin resistance diet - that everyone is raving about...
<3 chubbs lol
