I find the better I am feeling about myself the happier I become. things I let slide throughout my drinking career now fixing them and sorting them out give me the most joy...bills or debts, fitness, home improvements, relationships and diet..sounds sad but I genuinely enjoy ticking things of my list.
I still have the fear of missing out, but instead of the fear of not having fun, partying or getting drunk. My fear of missing out is focussed on time with my wife and son, fear of losing more friendships, losing my job, health, holidays and many other things.
sitting down at the end of a day when you have achieved all you can is a much greater high than what resides at the bottom of a bottle.
