First, it helps to realize alcoholism is a disease with no cure that we will live with the rest of our lives - Sounds simple huh?
You may have heard the word "cunning" as a descriptor. The thoughts that our mind uses to try and rationalize drinking are devious!
For me, keeping alcoholism simple in my mind worked the best. Just be willing to accept that we cannot drink today; string enough days, weeks, months and years together and it does get easier (the disorderly thoughts part.)
And by the way, the gym is an excellent diversion!
Take care,
Dave
