re: Cold sore remedies...any way to stop one once it has already gotten going?

Abreva sucks. I had a prescription of some cream that I always kept, but my primary care doc retired and I had run out. Got some Abreva and it didn't do a fricking thing for it. Used it several more times on later cold sores with shitty results.

And it's ridiculously priced. Esp since it doesn't work at all.

ETA: Zovirax was the cream. That stuff is awesome.
