In my case I tend to be pretty much a loner by nature and not very social. Drinking was an attempt, I think, to loosen inhibitions but it was not successful at changing anything for the better. Mostly it was just a lost decade. After I quit, life got increasingly better as each year passed.
Other posters have joked about waking up and knowing that this is the best you may feel all day. I actually appreciate the fact that I will never suffer another hangover.
YEah, this may have something to do with why I'm a morning person now, but I do also enjoy coming home beat at the end of the day and falling into bed and relaxing. Sleep is my narcotic sometimes.
