herpes simplex, suppression
"For the last 10 yrs every 4 months the Devils Kiss (aka cold sore) starts generally in the same region of my lower lip. I tried everything under the sun and was prescribed ACYCLOVIR in the past with mild results.  I went to Doctor and got this drug prescribed to me, but by this time my CS was already gone as I was traveling, just leaving pink scar for months.  I waited and last night I noticed the red bump forming around midnight.  Took 2 grams immediately and went to bed with fingers crossed.  Woke up, and the sore had not progressed, was tingling but no swelling, no blister cluster, SHUT THE FRONT DOOR.  If you are reading this, MUST TRY."
