I'm happier since I quit drinking. I never thought that my drinking was standing in the way of my happiness, if anything I thought I would be less happy because I was 'giving up' something. I had to be more honest sober in order to recover and that led to me prioritising and making sure I wasn't doing things just to be a people pleaser.
And of course there is the obvious benefits such as improved health, both mental and physical, and just not feeling sick all the time.
I won't say it has been easy, but then nothing worth having ever is. But the difficulties and benefits kinda came in equal measures for some time so I never wanted to jack it in. I had to persuade myself sometimes though. It's a big adjustment and it is only natural that we tend to want to slip into old ways, but it is so worth sticking with it x
