if you're interested in an alternative...

bht seems to be doing well for lots of people-- even at low doses.
I don't have outbreaks so the fact that I don't have OBs on bht means nothing.

but some say it radically decreased their outbreaks and when an OB did break through they just put some bht on the sore.

and THAT is only $20 for like a 1-2 year supply depending on dosage.

CAN'T beat that!
