No, I was being completely serious totallysoaked...You can go read on and on, some people will say OMG 'teh awesome', some will say it is a dissappointment. The only way you are going to find out is try for yourself really. Whether it works or not for you will depend a lot on how bad you have HH, how well you take the side effects etc etc...
I took Gly for two years. It did work to a certain degree (sweat was not a profuse) but it did make me dizzy, disorientated and very dry mouthed. Good luck I know how it feels when you are desperate for a solution. I def built up a tolerance so as advised in the thread, take on a need only basis. Good luck and wish you all the best.
