Re: Supplements for better sleep.

5-HTP, GABA or melatonin. 5-HTP is particularly good if you have serotonin deficiency depression (depression with anxiety, perfectionism, obsessive thoughts, autonomic negative thoughts), although I'm not sure if it can be used together with Wellbutrin. GABA is particulary good if you feel anxious, stressed, overwhelmed and have tight muscles. Melatonin is particularly good if you are over 55 or your sleep cycles have been interrupted by something like shiftwork.

This article on natural treatment for depression includes an overview of these 3 and when you would use each one.
