Any drug store or grocery that has a vitamin dept. Ditto to the answer above :-) They are sold everywhere and inexpensive I got it at GNC. Just about anywhere. Try Wal-mart, any grocery or GNC. Yes you can. In pill form. It is much safer than sleeping pills. At most drugstores, near the vitamins & herbs i won it from a raffle. Why dont u? Local health food store.

Pharmacies have just started selling a type of melatonin called "Rozerim", as a type of sleeping pill, but it was useless to me. All of the above answers are correct. You can even get it at Dollar General stores. I buy mine at Wal Mart. Most drug stores have it.
