Come to think of it, I've quit two different addictions

Gambling
I won't go into detail, but I lived immersed in it for about 3 years, riding the ups and downs. Eventually, when I lost two large bills (2 million won)
One day, I just thought, "Ah, f*** this?" and quit.
Cigarettes
I had been smoking for over 30 years since middle school.
This February, I suddenly felt the urge to quit and did.
Since then, even when I pass by a casino, I don't feel the urge.
Even when everyone else at a drinking session goes out for a smoke break, I don't feel the urge either.
I think I might have a bit of a psycho streak in me.
