The melatonin is supposed to counter the flush reaction of the niacin. The usual dose is 10-20mg melatonin to 500mg niacin. There should be no grogginess from the Melatonin and no flushing from the niacin that's the right ratio, a little different for everyone.Thank you for responding. I have definitely done the niacin, niacinamide, and zinc. I have not done melatonin. I will have to look into that.
