I have an addictive personality. Something comes along, and I like it, and I get hooked on the feeling. As of late I have been tapping into my dormant alcoholism. In the past month I have bought a bottle of 12yo dimple scotch, which lasted me 4 days, a bottle of balantines which lasted me 3,and 2 bottles of sake, which lasted a day each.
A friend once said to me, people aren't necessarily addicted to the substance, more addicted to the escape from reality that said substance provides.
I am inclined to agree.
