Can you go back to drinking once a week only?

I’ve been drunk usually every Friday or Saturday since I’m 15. I’m 31 now. Being a student and after that unemployed for almost a year led me to drink a lot sometimes 3-4 times a week. The last few months basically have been drunk-hungover-drunk-hungover. Usually drink alone to enjoy my music and for some reason I don’t wanna be around people when I drink. Maybe because I’m shamed that even 10 bear don’t cut it sometimes. You think it would be possible to go back to just being drunk once a week like before?
