You could always exercise more so as to sleep better.

Here is a post from Jack_Three_Beans about getting sleep...

Sleep = Nyquil

Don't recommend getting hooked on it though.
At the beggining if I found I couldn't sleep I would take a gulp of Nyquil.

Its self medication, not many are going to recommend it, but if you absolutely need the sleep.

After a time you won't need it.
