Not personally but the bloke who used to do my decorating and odd jobs said it had changed his life.....got him back to work after an accident and injury to his back after nothing else worked. In the end he chucked up work when he inherited a small fortune.
I was offered it and not to put you off but I was told you gain a lot of weight so I'm bad enough and didn't bother. I bought myself St John's Wort for a year and found that helped me with my lows.
Just an update I took it the first night and it took me ages to wake up in the morning. dont feel as though i could take it if I had a busy day ahead of me.
