You could trying asking your doc to prescribe Ramelteon/Rozerem. From Wiki(clicky link)~
Quote:
Rozerem (ramelteon), FDA Approved 07.04.05 , can be used for insomnia, particularly delayed sleep onset. Ramelteon has not been shown to produce dependence and has shown no potential for abuse, and the withdrawal and rebound insomnia that is typical with GABA modulators is not present in ramelteon. Some clinicians also use ramelteon for the treatment of Delayed sleep phase syndrome.

Ramelteon is a melatonin receptor agonist with both high affinity for melatonin MT1 and MT2 receptors and selectivity over the MT3 receptor.
