Ohh the botox thing isn't designed to stop the sweating, just prevent a certain percentage of it. Anyway, it's something I'm considering, but I haven't (and maybe never will) commit to anyway. I know it's not for everyone, but as my choice, it is a solid option to fall back on... if I can't find another way of controlling it.
Besides, by excessive, I mean the sweat is rolling down my sides in just a half hour after a cold shower... just in moderate heat. At the moment - though I still hope it will get better, of course - it seems to me that I will never even be able to consider (for example) a job that involves wearing a shirt (there are already 2 jobs I've left due to sheer embarrassment, and I'm only 20!). When you put together all of the small daily things that I do to avoid the problem, it really is astonishing how much it affects me! And I'm fortunate enough that it doesn't result in BO, just being permanently soggy. My heart goes out to people who have smell troubles!
I will definitely try the Cypress oil, all I have to do is get hold of some first

Maybe combining it with bicarb would help?
I do think it is probably down to hormones. I'm an intensely emotional person, which is often another indication of hormonal imbalances (as far as I've heard, anyway), problems with my skin, etc all point to hormones as being the main cause. I've even tried stopping taking the pill to see if it has an effect (it is, after all, a collection of synthetic hormones)... but if anything, I'm sweating more! (Plus my skin is worse for it! Can't win...) Still, if there is a topical treatment (such as bicarb) to see me through for now, it would be a major bonus!
Anyway, I'll definitely see a naturopath once I'm back in the UK (only a couple of months now really), are they expensive?
