Red, for me it totally crept up on me--I thought 'I can quit anytime.' When my life had become horrifying and utterly out of control I decided to quit all at once and found out the reality--within 12 hours I was dealing with alcohol hallucinosis and a situation where I was in hell.
Everyone has a different physiology but no matter how you react the truth is that alcohol is xtremely damaging physically and mentally and the best thing to do is remove it from your life. Wishing you all the best.
