i consume a bunch of milk and cottage cheese but i dont eat/drink any before bed because the calcium can interfere with optimal absorbtion of my ZMA.
im pretty sure good old fashion meat is a nice, "slow" protein.
eating meat also lets me sleep easier since im not waking up to take a leak 3 hours later.
any high protein/fat meat is a good choice for me.
besides, i get plenty of shakes through out the day and some decent whole food is always good.
i like a can of chicken or tuna with my favorite fatty dressing..4tbsp of ranch. add a handful of fishoil and/or whatever healthy fats you like (udos etc)and you have a pretty decent bedtime snack.
you could even add some low-carb veggies for obvious reasons.
i have, in the past, actually had "bed time steaks"! nice...
