yes. alcoholics present narcissistic traits, but not all are narcisissists.
narcissisism is deep, and often uncurable. i have seen people in AA recover from their alcoholism and their narcissistic traits fell away. but i have never seen a narcisissist who drinks and doesn't get help get better, only worse.
it takes years... of comitted sobriety and stepwork (in my humble opinion) to clear away the hotmess of dual issues like this.
for the reasons ago outlined above...thanks Andrew!
