[Will taking medication stop my body from building up the strength or immunity to naturally fight herpes?]

Hi I've had herpes the past few years.  I'm currently single and not having sex.  When an outbreak occurs, I don't take the Valtrex (which in my experience clears it away quickly).  I allow for it to fully run its course and I'm under the impression that by doing so, I'm allowing my body to build up the strength/immunity to naturally fight the herpes.  Am I wrong about this?  Should I just take the Valtrex at every outbreak I have?  Or am I really doing myself good by not taking it?
