P90X

I am starting P90X tomorrow. Have done insanity for the past 60 days and was very happy with the results. I was only taking in 2400 calories whilst doing insanity. Now with P90X my calories are 2988. Im 5ft 11 and weight 198lbs.
I know I will need these calories but its a little daunting increasing them.
I have decided to do the doubles. Doing insanity or running in the morning and then P90X after work.

I would like to get feedback from people who have completed P90X or just starting out too.
Please free to add me, it would be great to have friends who are currently using P90X
