its not worth it at all,dont buy into it.
there are much cheaper artificial methods to LD,viteman b6 is much more effective and much much cheaper,50mg a night works wonders.
BWG isnt worth it. sure it might help a little bit,not enough for what,45 dollars was it?
and if your thinking of cracking it,dont even think about it,the program is fitted with a alarm type system which will send your IP to the bwg company.
just leave it,the only thing it might be good for is the placebo effect it might give.
