My Doctors wouldn't prescribe it on a regular basis either - I could get 14 tablets that had to last 3 months 5mg each. I have never had any problems with the Valarian, but if you have racing thoughts and trouble sleeping and your head is a bit all over the place you might need a couple of go's to see if it works, otherwise it could just be a one off. Still worth a go for another 2 nights I reckon Kb21 and then if it still doesn't feel right for you stop.
Glad you got a bit of sleep though. I used to save my diazepam for emergencies too. I haven't had to use it since March 18 which is a good thing and yet I had had had problems for about 15 years before that..... so something good going on here - there is hope people!
