Anyone else take Lysine?

I have a cold sore right now (massive!), and I read that L-Lysine is great for helping to keep them away and to help heal them. I also read that Lysine increases the absorbency of calcium. Post-surgery, I'm taking a lot of calcium. It says to avoid taking large amounts of calcium and Lysine at the same time. But, this is for a regular person...I don't absorb the same way anymore. Do any of you take Lysine? 

yes, just when I feel a cold sore coming on or while I have one. I have not had a problem with it.
