I have been presribed it to help me sleep as well as been having headaches and couldn't sleep.
I was very brave (after reading the side effect leaflet lol) and took one. whether they actually worked or I felt better because I took it, I actually slept well last night, I slept from 11 - 7 which is unheard of. I feel a little tired this morning and feel like I have a slight hangover, but it could just be the fact I slept well.
