Zolpidem - and other sleeping pills may be associated with sleepwalking, sleep-eating and other unwanted behaviours. I'm interested in the stories anyone may have concerning any psychoactive pill.
SSRI's (serotonin reuptake inhibitors, or similar compounds) - these sometimes work as treatments, but may also cause somnambulism or sleepwalking. Again, I'm interested in any user experiences.
Also, probably more rare - anti-hypertensives, blood pressure control pills?
