Insanity Program (60 day)

Hello Everyone!

I just finished Week 2-Month 1 of the Insanity program. So far, I've lost around 4lbs. However, the nutrition plan and the workouts itself is getting more difficult as the days go by.
Has anyone done this before, or is going through with it? If so, what are your advice and tips on surviving another 7 more weeks?

Thanks
