Trying to quit drinking so much

Hey yall, I’m 28 and I’ve decided that it’s time I stop drinking so much all the time, but I’m having a difficult time with not buying alcohol. I can go weeks without it but the second I receive any money that’s enough to get a drink, I go and buy one. Does anyone have any advices on how I may be able to curb the temptation/cravings? I really do want to get better but I’ve found that it’s extremely difficult. I’ve been drinking since I was 10, and it got more consistent throughout the years, by the time I was 13 I was drinking everyday. Now I’m 28 and I want to stop but it’s extremely difficult. If anyone has any advice I will appreciate it greatly if you could comment.
