Struggling with Sobriety: How to Cope Without Alcohol or Marijuana

How do you deal with being completely sober? I have never been a drinker but I did used to smoke marijuana couple of times a week. However, I had to stop because all jobs I can get in my field require drug testing. I noticed that lately I need at least one drink of alcohol every day just to give myself a “break” from reality but I also know how bad alcohol is for your health so I want to stop. I tried picking up on reading again, movies, shows, exercise… but nothing really seems to work. I think it’s so stupid that companies are still drug testing for thc when it’s pretty much legal in every state and you can even buy it at gas stations.
