Someone close to us who is an alcoholic (although I don't think we realized until now the extent of it) was planning on going to 30-day inpatient rehab next month. He apparently hasn't had a drink since Sunday, and we found out today that he has been in the hospital since yesterday being treated for DTs. He's on Ativan and Haldol, and is hallucinating. We just learned that he had a seizure and is being transferred into the ICU.
He's relatively young (35ish) with no obvious comorbidities, although his doctor said that he was severely dehydrated and malnourished.
How worried should we be?
