Rusty, I'm sorry it didn't work for you either.
I got that fungus initially swimming in high school. I used a product made by Rexall drugs called FungiRex... It worked and I had no more outbreaks of athletes foot or nail fungus for years. Then, 17 months of combat duty solved that. I now have 8 of 10 toe nails affected.
The stuff the Service used to rid your feet from rot was killer in more ways then one. Yes, it did kill your fungus but it ended up putting me in the hospital for 3 weeks with highly elevated liver counts and my urine turning brown. Apparently, my kidneys were going into failure too. They made me drink a quart of mango juice 6 times daily.

I can't stand the stuff now. My liver enzymes are still not right after 22 years. Kinda puts a damper on scotch too.

So,... I drive a CTD for kicks.
My understanding is that the prescription pills do the same thing. For me, not a good choice. I'm going to try the ethylene glycol method and see what results it yields. I had a Sargent in the motor pool that swore he never used anything the service gave you for foot problems and substituted EG instead. He died from lung cancer because his one passion was Camels.
I 'll try using antifreeze starting tomorrow and keep you guys posted. Eg is highly toxic and also causes liver disease if swallowed. No... I'm not going to drink it, just apply it to the nails.
