I know everyone is different. My cold sores take place between my nose and my lips; there are some triggers I found out.
Those are:

  • almonds in every form (tarte au chocolat, amarettini, almond milk),
  • chocolate, dark and light,
  • sugar in higher doses than I’m used to,
  • the first and last days of my period.

Besides avoiding those triggers when possible, I take a L-Lysine supplement almost every day. I bought a massive amount so I’ll be fine for a year with one jar.
