1Anger sends people back to the thing they had stopped, and the thing they had stopped makes the anger worse. Any plan that treats these as two separate projects tends to come apart.
Write anger into the relapse plan by name, alongside the parties, the old friends and the difficult anniversary. Then when you look at the anger, ask what had been drunk or taken in the days around each flare. Both questions belong on the same page. It is rarely that someone lacked willpower on the day, it is that each half of the loop keeps quietly restocking the other.
Islamic evidence
Do not follow Satan's footsteps, for he is your sworn enemy (Quran 2:168). Footsteps is the right word for it, since neither of these ever arrives all at once.
“People, eat what is good and lawful from the earth, and do not follow Satan’s footsteps, for he is your sworn enemy”
Qur'an 2:168
Psychological evidence
In a laboratory aggression task with 69 couples, intoxication acted as a disinhibitor and amplified the effect of anger rumination on aggression towards a partner. The two did not merely add up, one made the other bigger. It was a lab task with a modest sample, so it supports the shape of the loop rather than telling you how tight it gets in a real household.

Why it works. Each of the two makes the other more likely, so working on only one leaves the wheel turning.
When not to. If use is heavy or daily, treat it as a medical matter first and get proper advice before changing anything.
