I am a bit nervous about melatonin; my doc (naturopath) recommended regular use when I was diagnosed with cancer, I tried 3X and each time I felt as though on heavy some drug for 24 hours, even with a tiny dose. Dizzy, hard to walk even, totally drugged out. I get very weird reactions to all kinds of things. I tried 3 times, thinking maybe something else. Nope, just the melatonin did it.
I did take some things last night (quecetin, zince, two herb formulas) and felt much better today.
When I take more than a few mg of melatonin, I literally have dreams about purple dragons. Not that that's a bad thing.
