ElChupacabra I can speak from experience that the earlier on quits drinking the easier it is.
When I was 23 I quit drinking for a year & 1/2, it was kind of hard, but not real hard. Of course that whole time I continued to want to drink and eventually did again. Well by the time I turned 42 quitting again seemed like a good idea, well I could quit some times for up to a month, but it was impossible to stay stopped so I would always figure "I can control it now!" so I would start drinking again.
Every time I started drinking again it was as though I had never stopped and it continued to get worse. It also got harder and harder to eve stop for a week........ by the time I was about 47 I could not stop no matter how hard I tried, I had crossed an invisible and HAD to drink daily just to feel normal!
In very simple words, the longer one drinks, the harder it is to quit, eventually one will need to be medically detoxed to get sober, I did.
