Wow...sounds like no fun at all. I would first suggest you stop taking the metabolife and sleeping pills. It may take a couple weeks, but your body needs to get back into a natural circadian (sp?)rhythm.
Definately see a doctor. As you said, you may have not been ready for the Paxil at that time. My wife was on that stuff and it made her sick as hell. There are other medications out there that may help you out.
I spent 3 years as a psych major before I switched majors (stupid move!)...If you want to talk a bit more about this, feel free to PM me.
I'll try to dig up my DSM IV.
