I did not yet find a source for 300mcg slow release, I take 300 mcg vanilla melatonin. I take melatonin in syrup/drops form -- it is jus that I take 2 or 3 drops (150mcg each) instead of 10 or 20, as is advertised. I was saying that I'd love to find a source for slow release, because then I could first take the melatonin drops, and just as I would be about to sleep, I would take the slow release melatonin -- that way, I'd extend the 5 hours to 6 or 8 hours of good sleep.
