All Day I Go Go Go, When Its Time To

All day I go go go, when its time to go to bed my body still wants to go, I would like to know how to relax and fall asleep. right now I take a Hydro to relax, they do work, I sleep good but I would like to stop taking them. I have tried a Hot cup of milk doesn't really work, Can you please tell me what I can do to relax before bed? Thank you Heidi
