I don't know what dosage you got in Melatonin. I buy 1mg tabs from source naturals and break them in half. My remedy is low dose melatonin. Years ago before I knew what I know now, I bought some melatonin and don't recall the dose but I took one and it made me really groggy. This was over 20 yrs ago I think. I never took it again until years later when I really got into this alternative healing world. I have no side effects with what I do, but nice sleep. And if and when I wake and can't get back to sleep quickly I pop a calms or an inositol.

I know we are all different.
