I have to go to the dentist today.... I am very very phobic, I broke a tooth over the weekend and a big filling has come out. A friend suggested taking valium (diazepam) before I go to chill me out a bit,DH has some in the cupboard. Is it ok? Have you done it? half a tablet or a whole one? never taken it before.... HELP!!! have got the rescue remedy ready as well.... but am shaking already!
