Used to raise sheep who got foot rot. The only cure was to get them to stand in a solution of copper sulfate and warm water for 10 minutes twice a day for three days. It cured the foot rot about 98% of the time so give that a try for your toe nails and let us know how that worked, just note the copper sulfate will turn your feet blue but should wear off in a few days or so.

Terbinafine, Ketoconazole, Fluconazole..

Go see a general practitioner at least, and a dermatologist if you can.  God gave us the knowledge to make and use medicines.  

Sure, you can take hydrogen peroxide (which is rocket fuel, btw), which may or may not work after a few months once there are no toenails left.. or you can go to the physician, take 14 days of medication, and be done with it.

Idiot

Idiot

How very charitable..
And what, pray tell, is so idiotic about taking antifungals for a fungal infection?

I think the topical medications work best.  And removing the dead nail, while applying the topical directly to the fungus helps a lot!  Of course, antiseptics will kill fungus too and normal hydrogen peroxide is very good at killing fungus and is very cheap.  It says on the bottle of hydrogen peroxide that you can gargle with a solution of it, diluted with water.  I don't know anything about drinking it.  

What's the deal with soaking your feet in baking soda or vinegar?  I tried salt water foot soaks and, while they seem somewhat effective, I thought the prescription topical Penlac (which comes in a generic and is relatively cheap and should be approved by all/most insurance) was effective, but of course, not a cure.  Apparently, there isn't one.  However, Penlac does seem to be good at forcing the fungus into major retreat and it seems that I can go for months without applying any and still be in pretty good shape.  Still, for now, it does seem like a "life sentence."  

I notice that the fungus seems to spread from the nails to the skin, if left untreated for a while.  However, I use a generic/drug store brand spray with Miconazole for the active ingredient and that seems quite effective.  Some of the other anti-fungal sprays don't seem to work for me, like Tinactin, which has a different active ingredient (turns out it isn't so tough! ha ha). 

Apparently, toe nail fungus is "contagious."  So, if you pick at your nails with your fingernails you can get it under your fingernails too and if you scratch at your legs, it seems you can wind up with fungus growing on your skin.  Hence, I often sleep with a loose pair of socks on.  I am always careful to use nail tools and clean them with hydrogen peroxide when I am done and of course, dedicate a pair of nail clippers to toe nail duty only.   

After use his socks should be soaked overnight in fungicide , then washed and used again only when thoroughly dried

This may help somewhat

In a very old medical book. It was short and to the point.  the symptoms maybe that of an inflammation from within.  Why it shows on the bottom of feet, I don't know.
All I know is that it worked for me.  I did not have fungus or spreading of the fungus or loss of nails.  What I had was very dry cracked skin on my feet.  By cutting out red meat, sugars, glutens, grains, it clears up.

Yeast needs to be researched as well.  You try to care for the problem on the outside, but also finding out what can aggravate the situation can be very helpful.

Also go to the site of The Doctor Within. That site is full of very good knowledge.

He is already on a gluten-free, sugar-free, ketogenic diet.
We are also using a Mineral Infra-Red Lamp (Dr. Chi International). He uses this every night before bed.

Maybe check out chelation therapy?  If there were oddities in his antibiotics, chelation can help clear out those bugs, metals or such.  Read on chelation therapy.
