Did it on Monday, as I have a do next Monday. But so far, all that's happened is the skin looks rough, dry, and a little bit's peeled off the side of one foot.
So do I:
a) soak them tonight and see if they start peeling tomorrow?
b) do another one (different brand) tonight, and hope it kicks in and works over the weekend?
c) do nothing and wait?
Gah. I have got shoes to wear rather than sandals, if the worst comes to the worst.
