Don't take any drugs. Except Melotonian.
I have learn to control my sleep to the effect that I can get dreams when I want them. The secret to sleeping quick is to try NOT to sleep. (The drug I listed above is anot a drg is is an increse of a natural chemical your liver produces that streches you sleep cycle out... use it.
Once done try to stay awake... unless you are silled in meditatin.. you will fall asleep... Happened many times to me... almost every night... it's VERY VERY hard to shut your body down and keep your mind awake.... 95% of the time I sleep first...
Despite onlt getting 4-5 hours lseep on weekdays I still feel somewhat relaxed by this ,ethod.
