If you drank while playing video games or watching videos all the time, those activities would also be difficult to do without thinking about alcohol.
I'm also a writer and one of my rules was to never drink while writing, because I didn't want to only be good at writing while drunk.
You have to relearn to enjoy doing things without alcohol. It's like starting back at 0. It's too bad you didn't have someone tell you when you were younger, it's harder to do things when you're not in the state of mind you learned to do them in. There's lot's of people whose second language only improves as they have a few drinks, because they only ever talked in the other language while drinking. Does not mean drinking improves your ability to speak or learn one bit, haha.
Drugs as an impetus for creativity is a pretty damaging myth. The correlation between drug use and creativity exists largely because of the myth itself.
