My husband quit drinking (except for 5 glasses of wine, over time) Feb,2008. Since then he has had episodes of lathargy, tiredness, and appearing very much like he did when he was drunk. He has been drinking for aprox 50 yrs, and is 70 years old. He will be fine, and then I will see a glaze come over his face and he becomes incoherent. His doctor has given him an MRI, and he has no sign of stroke or tumor. Are these typical symptoms or a person that attempts to quit after excessive use for a long period of time? Also, his tolerance level changed, which made him stop in the first place, along with family intervention.
