Hi lybrate-user! Addiction cannot be stopped by just getting a suggestion, you need to undergo de-addiction program just like alcohol or drug from de-addiction center or from a Professional Psychologist
at your locality. The best way to quit is to undergo treatment for the same.
If you wanna do it by yourself it would require consistency, will power, strong mindset and hardwork irrespective of pain
, if you feel it would be very difficult to control by yourself then you can seek Professional help.
