I am exactly in your position. I have spent countless - and I mean countless - hours of researching ETS due to my generalized sweating, nervous sweating, blushing, trembling, palpitation and regular feeling of anxiety when among people. I have also spent countless hours and thousands of dollars on hospitals, acupuncture, all kinds of remedies.
I know how much this **** gets us down. I know how crap it is, never to trust your own body, always worrying, give up things like dating and parties, job and education. To this day I am still tempted to go through with the surgery but I have not - and I will tell you why.
Being a generalized sweater, the operation will mess our bodies up even more. i don't know about your state now, but I will sweat from chest/back easy when nervous or when in hot weather. When mutilating the Sympathetic Nervous System, it is unavoidable with reflex sweating. For people that didn't suffer from heavy body sweating before, that can be a good trade, but sometimes even for them, reflex sweating will be unbearable.
The mechanism of reflex sweating is believed to be: You get hot/nervous --> Your nerves send signals to your body to sweat or to "defend" (flight or fight response) --> You will not be able to sweat or you will sweat less on the upper third of your body --> You get drenched everywhere else.
The mechanism works as such, if you are nervous, the signals will be "kept" in the lower third of your body (depending what level you cut) and instead try to "get out" there. People with severe reflex sweating are still handicapped because they will sweat even more than before when nervous.
And we my friend, are in the risk zone of being there.
Even doctors Telaranta and Lin - described as greedy by many - say that they can not avoid reflex sweating in my case. And maybe not in your either. Certainly not if you cut/clamp T2.
You have to understand in the end that even if you talk to other people, it is no guarantee that you will be as happy as them. Or as sad as them. It is all down to individuals, everyone will react different on the operation - and we have the odds against us.
Every night when I sleep, every day when I eat, every morning when I wake up I curse this state - it consumes me. But still I refrain from the operation.
Because when it's done there is no turning back.
