I've been doing a pretty intense program where I do Body by Science on Mondays with machines and a routine on Fridays with free weights 3x5 (bent rowing, overheads, bench, pull downs, squats) and 1x5 deadlifts. I really feel the workouts for few days and am sleeping really well. The deadlifts are especially deadly.

So, I'm wondering how I should regulate by protein intake with this schedule. Can I assume I should eat lots of protein on workout days and the day after? I know that it can take a whole week to completely recover from deadlifts, but how long do I need to do more protein? What about IF relative to a two day intense lifting routine?
