How can I make sleep medicine?

Is it possible to make any medicine, therapy, or something that could make you feel you've had enough sleep even if you haven't actually been sleeping?

• Is it possible to "sleep" without get actual sleep?

• Answer:

  The traditional approach to compensate for lack of sleep was brute force application of stimulants such as amphetamines.  In other words, the approach was to decrease sleepiness since not as much was historically known about the brain systems that kept us awake. This changed in 2002 when the FDA approved http://en.wikipedia.org/wiki/Modafinil (Provigil) for its ability to "improve wakefulness". Modafinil is a drug that disrupts multiple neuronal systems.  It increases levels of dopamine by fudging with dopamine transporter reuptake, it raises histamine levels, and it has been shown to reduce GABAergic tone-- all three symptoms of a good wakeful state. Nothing exists which can replace the biological imperative which makes sleep so necessary, but drugs like modafinil can improve the quality of wakefulness for those suffering from sleep disorders, or for those who have to remain awake during extenuating circumstances where sleep is not an option for at least a couple of days.
