You have to be very careful with St Johns Wort, go into Holland and Barrett health food shop and ask for their advice. I was on medication for years but then I found Paul McKenna's books on I can make you sleep and if you follow it to the letter then it works but not overnight, I never thought I could feel good about myself again but Paul has given me the tools to get my subconscious to react differently and so to get that feel good feeling back. You can get the book and CD comes with it on Amazon, why not give it a try, for a few pounds it might be the beginning of a new you.
