I try to take consume about 20g of protein every 2-3 hours. Normally I eat solid food if it’s available, but if I’m in a hurry I’ll use a protein powder. There’s no special time of day to consume protein as far as I’m concerned. If you’re awake, you should be getting protein every couple of hours. Obiviously since you cannot consume protein in your sleep, getting some right before bed and first thing in the morning is important. Do not obsess about this though, sometimes I get tied up and don’t eat anything for 4-5 hours. It’s not optimal, but like someone said on another thread awhile ago, you’re not gonna die if you’re not getting protein every X number of hours.
