Botox (or any other means for that matter) would seem to be a far more sensible idea than ETS.

Although I may now have a problem, I've just found out that the US Navy has disqualified candidates for entry simply on the grounds of hyperhidrosis. Granted I want to join the British Royal Navy, so their policies may be different, and with any luck they might rate application on the severity of the condition... as opposed to simply disqualifying candidates just because they have hyperhidrosis (which is moderate - not severe - in my case). The candidate who has disqualified was rejected (as far as I can tell) entirely because of hyperhidrosis, and not for any other reasons, he was also being treated for his condition with Botox.

I'm going to have to get in contact with a Royal Navy medical officer to find out their stance on Hyperhidrosis (I do know that ETS had been used as a suitable surgery for Naval staff with hyperhidrosis... but I don't know if they still accept it). If they don't accept Hyperhidrosis sufferers or ETS, then I'm screwed either way... but if they do accept ETS I could be facing a difficult situation. Right now I'm hoping like hell that some other surgical alternative shows up in the next 5 years, because I only have till I'm 26 to apply.
