Excessive sweat in the armpits.?

I am a 28 year old male. I used to use Right guard, old spice etc.. Ive tried Gillette and Degree clinical also used Certain Dri. None of these products work. I dont wanna see a doctor due to money situation. What have you tried if you have had the same problem as me. Could it be i don't drink enough water? maybe 8 oz a day including food intake. Thanks.
