Thanks for the responses everyone. I'm on my first week of Klima but the company says it takes a month to get full results so I'll wait and see what happens.
I'm also using Drysol at nights so I don't know how accurately I'd be able to measure Klima's effectiveness on its own... but as long as the two can reduce my sweating I'll be happy.
I may also try secure wipes in the future. It seems like it gets mixed results based on people's reviews, but I may try and see, if Klima+Drysol doesn't work.
I used Avert in the past, but I felt drowsy and doped up on it... though it may have been because of other things I was taking at the time, and I also did not drink enough water. When summer starts I'm going to add it to my arsenal again and see how it works this time.
