I've had foot fungus for many years. It comes and then it goes. I use the drug store stuff, lotrimin or something, and it goes away. Then I don't do anything, it's fine and it comes back again. I feel like I'm on this endless cycle. I went to the doctor once and got a prescription and it helped - went away immediately. But, it came back about a month after I stopped using it.

Does anyone have any tips.
