Changing your routine or even your evening venue. Instead of alcohol being your reward, pick something else. Working out, going for a walk, a nice healthy dinner (or in my case early on a pizza! haha), pick something to netflix. Early on I found documentarys or shows related to alcohol to keep my focus. If you don't want alcohol related, pick something else. Go to an aa meeting, hang out with friends or family, read. Pick SOMETHING to look forward too other than alcohol at the end of the day. Do the same the next and the next and the next.
I had an app early on - a sober counter that was also motivation. Pick a sober family member, friend who knows what your sobriety goals are. Tell them. Check in with them and they with you. This helped with accountability.
