Canary in a coal mine

I've noticed that during stressful events in my life, that leading up to something big, or just completing something big that I get a cold sore.  My mom tells me that they're stress related.  Well I got one started and man does it hurt.  When I feel one coming on I overload on L-Lysine supplements.  If I don't they last a couple weeks, but with the early detection and supplements they last about half that time.  I figure the stress of organizing the race was too much for my body and its retaliating.  

This morning's swim was cut short.  Swam at SDRC:

2000 free

1000 - 5 x 200's odd IM, even kick no fins

2000 pull - using the crappy equipment SDRC provides

300 - 100 easy, 200 IM

5,300 yards total in 1:30
