You sound in the kinda shape that i was at your age.
If you are not an alcoholic then you may be able to drink for years with only a minimal effect.
If you are an alcoholic eventually loss, shame, guilt and ill health will be your bedfellows until you either stop or die trying.
For you to decide.
Just a word of caution tho.
If you are happy about your drinking, what attracted you to this site..... Mmmmmm
