Addiction is anything itself that falls under the category of NO-NO, to me. I feel that addiction to anything, let it be good or bad for your health, is NOT GOOD. Everything in life should be under a control system and should be worked accordingly. The more flexible you make your life, the more sustainable it gets is just my point of view.
I am happy that you were able to get away from your addiction habit. You were lucky to be conscious about it.
