Hi Over It,
I agree that Valtrex or other antiviral drugs are probably your best bet for minimising outbreaks, visible symptoms and viral shedding. You might also check out a (much cheaper) product called H-Balm which is a combination of essential oils that can be very helpful for some people. Do a search and you'll find it. It has a pretty strong odour to it, but you could shower just before you go to work to get rid of the smell.
In the meantime, I don't know how "intimate" you get with the audience in your dancing (I'm thinking you might be an exotic dancer, who sometimes do more personal, "off-stage" dancing), but if there is ever any skin-to-skin contact between your OB area and the audience, you might want to reconsider if this is a good idea. Even if you're not having an OB there you can be contagious, and if there are any visible symptoms (even redness) you could be shedding the virus there. ToughSpot's posts can attest to the possibility that herpes could be transmitted that way. Sorry if I have the wrong impression about your work, I just thought I should mention it, just in case.
Good luck! Let us know how you make out.
