Searching for an OLD story

For some reason this story popped into my head, but after searching my hard drive, and web.archive.org, I appear to be SOL.

The story involved a pair of women at a mountain to go skiing, and one passed out some pills that guaranteed to keep one warm. The girls took too many, and fattened up/inflated right out of their ski suits on the slopes.

If anyone has it, or can point me in the direction of it, I'll give you one shiny new internet.
