I guess he was on the Lysine for about 2 days before it went away completely, but again, I don't know if it was completely due to the Lysine, or if the other pills had a hand in it.
I don't have the name of the pill on me right now, but I'll look it up and get back to you.
In any case, give the Lysine a shot and see what happens - maybe that was it all along!
