I've been trying melatonin as well so I can take a break from the benzos. Unfortunately it doesn't stop me from waking up every 1.5 hours but at least I manage to fall asleep again instead of being awake for half the night. I'm not sure if I want to be taking melatonin long-term either though. Don't want to mess up my own melatonin production. I saw an article that said there's a link between bipolar and hypersensitivity in melatonin production as affected by light. That would explain why the long summer days mess me up so badly. It's kind of nice after having people tell me it's "impossible" to be so affected by it.
