I bought these items in this kit separately from Boots for about a fiver..
www.boots.com/canespro-fungal-nail-treatment-10153509
and I am on the way back to normal with 3 nails on one foot.
Its harsh - but it's worked - I would advise you start this in autumn when you wont be wearing sandals anymore,
I'd tried vicks, I'd tried other treatments, I even when to a chiropodist who said the only way was 6 months of strong tablets.
But you cover each toe that needs in urea cream and seal with plaster tape. and change it every day for 2 weeks. every time you can, you nail clip your nail down
-
- on my big toe I literally ended up with about 5mm of nail!! BUT it got it. and it's growing back fine.
I at the moment - stick a false nail on it (it;s grown about 1/2 way atm) in the same nail polish as my others and you literally can't tell 
As I said - probably better to just paint them over for summer and start this in Autumn.
