You should always eat 1.5 grams of protein per pound of bodyweight but you might want to drop your overall caloric intake a bit since your basal metabolic rate will go down slightly...
If I were you, I would keep the protein and cals high for (at least) 5-6 weeks post cycle. This should help your body get through it's catabolic state and minimize size loss. A lot of people make the mistake of dieting and cutting right after a cycle....they find out the hard way that it is not easy to keep your gains on a low protein calorie restricted diet.
Most of the gear that your taking will be in your system into your clomid + Just because of your coming off, doesn't mean you want to stop growing, Cut the cals down, keep the protein up and work out like a MOFO...
If you know what your doing, you drop the water weight and keep the muscle mass! It hard....damn hard!
I think by not doing this, this is why a lot of bros do not keep their gains!
