Since I started in '09, I haven't experienced this at all. However, I vape much less today than I did when I was breaking away from a 43 year 2-3 PAD habit at the end.
Sunday I started feeling the effects of a cold coming on- kind of a sore throat but not really. Yesterday really felt bad and when I woke this morning, the remnants of it plus a headache. I grabbed my PV early and have been using it consistently this morning. I've found this technique has helped me get past a cold in a couple days. We'll see if it works this time.
I can see if you're vaping constantly during the day developing issues if you're inclined toward those issues and particularly if creating heavy clouds of vapor are part of your technique. I go for flavor and minimum visible cloud. I go through, at most, a ml a day at this point.
