Hello, Welcome to Health Care Magic. I understand your concern. Alcohol is a very powerful addictive substance which produces physiological and psychological dependence when consumed regularly for few weeks. Your wife is drinking daily and apparently she has increased her drinking level gradually as tolerance to the effect of alcohol would have taken place. The person habituated to drink have a strong craving for the substance and whenever they stop drinking they experience withdrawal discomfort in the form of insomnia, anxiety, restlessness, palpitation, excessive sweating, tremors, nausea, anorexia and sometimes even hallucinations. Due to strong craving and withdrawal discomfort the habituated person usually fail to quit drinking. Any way daily drinking is not advisable due to harmful consequences of drinking on body, mind, social and familial relationships and occupation. Gradually alcohol brings several harmful changes in brain which brings a change in personality over a period of time. Irony is that the people habituated to drink have very little insight into their illness (Dependence) and they never acknowledge their problem. Daily drinking and often showing behavioral problem after drinking is a sign of dyscontrol over her drinking habit. Your wife certainly needs help of a psychiatrist at the earliest for de-addiction therapy. You may also motivate her to join Alcoholic Anonymous group (a group of reformed drinker who motivates others and help others to stop drinking) in your locality and to attend AA meetings regularly.
