I've tried it and have still got it. I haven't found that it's worked for me, but then I haven't really given it much chance to work either. Apparently it can take up to 2 weeks continuous use to work; I've never used it for 5 days straight . How long have you been using it for, dsf? And where did you get it from? I got mine from Holland and Barrett - do you have that in NZ?
