I’m not a man so I can’t give very much advice, but if it helps you to take a look at your diet. It is possible that you are too desperate to find the right antiperspirant for excessive sweating and it may be better to take a look at your diet first. Are there any foods that make you sweat more? Is there anything that makes your skin feel drier than usual? What about drinks – coffee, tea or alcohol – do they make you sweat more? Are there any medications (diuretics) or supplements (e.g., vitamins B6 or magnesium) that could be affecting the way how excretes perspire? If this doesn’t help then definitely check with your doctor as he/ she might know what medication(s) could be causing this reaction in case of an extreme case like yours.
