Here’s my advice as someone that quit drinking about 6 years ago due to my inability to drink responsibly.
Do you want to quit? If you feel like you can’t handle playing a game in moderation, maybe it’s time to think about quitting it entirely. If you feel like playing other genres of games will eventually draw you back into playing more addictive games like WoW, then you could think about quitting that too, it’s up to you. If certain music makes you think about playing WoW and you can’t control yourself if you listen to it , make a sacrifice and don’t listen to it. I avoided bars for years and still don’t really love being around when people are drinking. The sacrifices I make are well worth it though and I’m much much happier as a result.
Have a long, honest conversation with yourself about what you want from life and how video games fit into it. That’s what I did with alcohol and realized I didn’t want to waste my life on stupid shit any more and decided to quit.
