Why is not drinking so hard
It is hard when you do not have the tools to stay sober. It gets easier the longer you are sober and the more tools to have in your toolkit. Having a sober/recovery community is really important for sobriety, too.
Lifestyle change
Do the opposite of what your doing get out meet people and friends at aa meetings. 90 meetings in 90 days.reach out.people want to help.we need to change.and do the work. Do something but stay sober.
It's hard because it's socially accepted and because of that It's everywhere. I recommend reading Alcohol Explained by William Porter. It's easy to read and understand how alcohol affects you. Best of luck
