Brett, This site: mentions SSRIs (anti-depressants), but they also say it's completely inconclusive.

From Wikipedia:

Possible causes

Little is known about the physiology of sleep paralysis. However, some have suggested that it may be linked to post-synaptic inhibition of motor neurons in the pons region of the brain. In particular, low levels of melatonin may stop the depolarisation current in the nerves, which prevents the stimulation of the muscles.
There is also a significant positive correlation between those experiencing this disorder frequently and those suffering from narcolepsy. However, various studies suggest that many or most people will experience sleep paralysis at least once or twice in their lives.
Some report that various factors increase the likelihood of both paralysis and hallucinations.

These include:

Sleeping in a supine position (facing upwards)
Irregular sleeping schedules; naps, sleeping in, sleep deprivation
Increased stress
Sudden environmental/lifestyle changes
A lucid dream that immediately precedes the episode

And this link is from that link:

Maybe you should talk to your doctor and see if he/she knows something about this? I wish I knew more about it... Or maybe there's a sleep disorder specialist near you, some hospitals have sleep disorder clinics.
