Thanks, though 3 years later this isn't a problem for me. I still don't know why it was then. Nowadays I just use some generic spray antiperspirant/deodorant and I'm fine.
It worked well. I stopped using it a while ago but I remember it being helpful. I don't know if I'd recommend it as a permanent thing though. It's pretty potent and I don't know if it's good to use every day on your skin.
This is what I use but I use the Swagger scent. This is the only deodorant I have found that actually keeps the underarm sweat under control. The downside is over time the stuff seems to build up on the pits of my shirts and eventually I have to throw them away because it gets noticeable or uncomfortable.
