Excellent letter. I also have a small addition. There is no such thing as dopamine addiction. Dopamine is what keeps you reading the rest of this sentence. We need it to function, to accomplish mundane tasks. While all addictions are based on dopamine, it's not the dopamine itself, but the habitual or substance induced dopamine reward you can get addicted to. I recall discovering the fun in small, mundane things somewhere along the first few weeks of my recovery, once the unfair PMO dopamine reward kept missing. If you find a better way to express what you mean, that would give him one thing less to point his finger at.
