I got the liquid 10mg kind from Vtmn Shpp. High dose because I worked up to 100mg per night:
First night, 10mg
Second night, 20mg
So on, until I worked up to 100mg. I did this for one or two weeks and then worked my way back down the same way (90mg, 80mg, 70mg, etc)
I was shocked this helped so much, because I'd previously tried melatonin at the meager recs on the packages.
