I saw the rash etc. he got but from what I've read off american research, cases of a bad reaction to the drug are very rare. I wasn't sure if it had been licensed in the UK either, all I know is that it has been in the USA. I used to suffer from chronic insomnia from when I was about 16 till last year and I have to admit that although I feel better that I'm sleeping properly, I feel like it's still a bit of a waste of time!
