It seems there just is not enough time in the day to get 8-10 hours of sleep. If im only getting 6-8 hours of sleep each night how with this affect my cycle results? My diet is strict, and my protein intake is around 300-400 grams/day. Granted your body needs down time to assimilate the protein and what not, but is sleep really as big a contributing factor to overall growth as some people state?
