They are certainly not triggered by sun exposure...it's winter down here . I've never really been able to pin down my triggers as I don't lead a stressful life and I'm not a sun worshipper. I just feel at the moment that it must be diet related.
I'm currently taking 1000mg of the l-lysine and will discuss it with my doctor when I go for my first checkup since starting this WOL. Does l-lysine occur naturally in any foods?
