Over the last 3-4 years, I have really made it a point to be a lot more conscious about my drinking. And figuring out what drives me to drink and figure out alternatives. I can easily go a month without a drop of alcohol. And as you mentioned, I felt better overall. More energy, better sleep, more focused and in a better mood. I wake up earlier and much more productive. I hated wasting days by drinking too much, going into a fog and getting real tired. Watching tv shows and having no real memory of what I watched. And as I got older, the hangovers are worse and last longer. The brain fog where it feels like you are going through the motions in another reality gets old. Kind of ruins the day. My concentration and awareness is lower. Too many wasted weekends with alcohol. Also much easier since my fiancee rarely drinks. Previous relationships, my significant other were heavier drinkers and we felt we needed to drink at home, bars, etc. Needing alcohol to have a good time.
