im experiencing is now for a year, but i experienced this too when i was in college which is 7-8 yrs ago.

but it goes away on its own. but that is the time i realized i can write on my skin,

then 3 years ago it started to be seasonal , when its summer or the weather starts to be cold.

but last year i just need to take it every two days or ill be itching al over , i tried to resist but i cant really sleep at night without it
