To my knowledge, they try to take drugs (if the home has the $$$) to keep the symptoms away, just like other people.
Other people "trust the lord" and try not to "share" when they're having an outbreak.
Yet others don't tell anyone (I'm sure, because so many people have'em. But especially the FGA's)
But I think they should quit sharing outside of their marriage (besides the young singles, who should be entitled to sex with other singles -- if they want that).
