I usually buy my beer with a credit card. So I guess alcohol has helped me to get an 800 credit score.
I gave up alcohol & smoking years ago and still think about it everytime I walk by a bar or smell a cigarette burning. I would take an 800 score in a heartbeat over those 2.
I'm still working on my 800 scores.
As someone who has worked for nearly 5 years to repair credit from what should have been a medical bankruptcy - and I didnt know better so I didnt, yeah I would give up drinking for an 800 credit score. I rarely drink but I have a several a day soda habit I would throw in too - for an 800 credit score. 5 years in and I still am not to 700, getting close but not there. To be fair, there is little I wouldn't do for that score.
