People react to alcohol differently. I personally stopped heavy drinking because it causes me to enter a semi-conscious state where I honestly believe I act as if I am in a dream state, with basically non-existent rationality. The result was personal injury and property damage in college and that was enough to know to stop. (Thankfully when in this state of mind I never hurt or abused other people, I generally was either super friendly or verbally hostile, but in any case had minimal recollection or explanation for my behavior.)
