I'm taking NT too, and I usually cap at twice a day (NT is expensive compared to ON and other brands), so to maximize the intake I usually drink 1 scoop with milk first thing in the morning to 'break fast' as the body is very receptive to protein at that time; and the second time of the day is within 15-30 mins post-workout to maximize recovery rate and muscle synthesis. If you want to drink protein before bedtime, NT is a very very bad choice as it's considered whey, if you must take in protein before you sleep, opt for casein, it's slower-digesting protein and can release a stream of protein throughout the night when your stomach is empty, this promotes muscle growth instead of like whey where the protein will go BAM! *gone* under an hour.
