Nope, I have not. Now back in the day before the ephedra bann I did and it worked just fine. That was then and since the bann I never found another over the counter product to work the same.  I personally would not waste any money and trust me I wasted some major money in the past  , (unless like your doing) some research first, which is a smart move.  See if they have a money back guarantee now that would catch my eye if it does not work then you can get your money back.
Hopefully others will responde.  ttyl c.c.
