these bothersome infections are not really nasty - but is there any other tangible option other than those really expensive antifungal drugs - Sporanox (itraconazole) and Lamisil (terbinafine)?? i also have heard of a nail lacquer called Penlac - i just think these treatment options are just too bloody expensive!!

You are not alone Amo. Nearly 1.8 million people in the UK suffer from nail fungus. And toenail fungus treatment can be very expensive.
I have found one thought, from Waldon Research, a company in the USA that sells here in the UK has designed a product that not only kills you’re the nail fungus but substantially increases nail growth in the time after the fungus is dead, so that the new healthy nail grows through at an accelerated rate.
Although I have tried many other treatments the treatment is not complete until the new nail has grown through. This can take many weeks. Until the new nail grows back it will still be scarred by the previous infection, it can look discoloured thickened and cracked. The Waldon product is the first to recognise this part of the process and to speed up the new nail growth, so you will have beautiful, clean nails again.
Waldon Research’s product can be bought online without having to visit a GP. It is only £19.95. Since Waldon are the manufacturer, the cream comes directly from them with no middlemen involved, and I think that is the key, cutting out the middleman. Some other treatments, where the manufacturer and the supplier are different companies, can cost as much as £100.00, as you well know! I really have found it very effective, so it may be the answer that you want.
