Thread: Melatonin and dreaming

Melatonin seems to lessen dreaming in the first half of the night, and increase it in the second half. In my personal experience melatonin is not much of a lucidity booster. By the way, it seems the most reasonable dosage is somewhere between 0.35 and 0.5 mg. In the US melatonin is frequently sold in dosages up to 30 mg, which seems excessive in a way that words can not do justice to.

Vitamin B6 seems to be safe in dosages up to 100 mg per day, taken over longer periods of time. 200 mg would be borderline possible for short spells. Anything higher is simply asking for (painful) trouble. 1000 mg most likely causes immediate pain (and the nerve damage pointed out by MoonageDaydream).
