Is it possible to sleep too much?? since sleeping is catabolic?? like lets say throught the day is it ok to take 2 hr naps??

I believe it's only REM sleep that is catabolic, and this doesn't occur until 90-120mins into sleep so you should be fine.

i can never get enough sleep. good rest is a great thing id say.. how many hours do you sleep for each day/night?

is it a must as in is it absolutely necesary when the goal is to get big??
