Hi Zero, Yes I have tried it, I sent away for it.
I still have half of an out of date bottle in my cupboard. It was expensive, i couldn't get it in Oz and had to get it from OS.
I cant say that I benefited that much, at the time I was motivated to stay sober and I was looking for any sort of support. My thinking at the time was this sounds good, a pill can do the work for me. It was about 4 to 5 years ago. I cant recall the other benefits.
I would say if moneys not a problem give it a try, it might work for you. Not so much for me.
