Starting P90X on 4.11.13, anyone else?

I am due to start P90X on 4.11.13, just preparing myself for it now.... If anyone else is due to start or has started recently it would be great to exchange advice and support during it!! I have recently completed Insanity and loved it, so I am looking for a new challenge :) So far working out the nutrition guide has been the trickiest part but I am going to work so hard at sticking to it. I hope there are others out there that can share their experiences of the programme with me!
