Caffeine, like alcohol, can temporarily spike dopamine production in the brain, resulting in a pleasant feeling. Or, for those of us accustomed (addicted) to alcohol and the dopamine spike, caffeine helps take away the bad feeling of lower dopamine levels. Nicotine can do the same thing. Coffee and cigarettes are quite common staples at AA meetings.
