Dissociation Anonymous looks at alcohol and drug myopia (Altered States)

Dissociation Anonymous looks at alcohol and drug myopia in alcohol abuse in which many of alcohol's social and stress-reducing effects, which may underlie its dissociational capacity, are explained as a consequence of alcohol's narrowing of perceptual and cognitive functioning.
One of the greatest challenges of dealing with chronic alcohol and drug abuse is the feeling of isolation and aloneness, and experiencing something that so few understand. Many more of us deal with chronic abuse than most of us would imagine. There is also the challenge of experiencing something that you have little or no control over, which can elicit feelings of fear, rage, depression, and victimhood. One also becomes more vulnerable to the darker impulses of the mind as it struggles to adapt to the day-to-day realities of what often feels overwhelming.
