Hi, I had the same problem for years. I finally went to the doctors about 3 years ago and he prescribed me a deoderant containing aluminium called Anhydrol Forte (roll on), it is fantastic! You only use it at night and start by using it 2 nights on, 2 nights off. Then after a few weeks you should be able to do 2 nights on, 4 nights off, it is so good that now I only use it once or twice a month. Remember to wash it off every morning and apply your normal deoderant. And if you have sensitive skin like me, rather than applying the anhydrol forte like a normal roll on ie roll up and down your arm a few times, only roll once ie roll up your arm once.
I know how you feel aliczech, I wanted to wear light airy shirts to work or light summery tops and before I had even made it to work I had dripping wet armspits and big wet patches. Its so embarrassing.
PS, you dont need to have a prescription, you can go to the doctors/hospital chemist and just buy it.
Hope this helps
Kim
