Hi, I am so sorry to hear about your husband and know what a fright it can be to sit out there and wonder how things are going. Not to sound as if your concerns are not accurate but the people in the ICU are pretty busy and then they aren't really suppose to be talking too much about medical info to you. They usually ask my husband if it is okay to discuss the issue. I don't believe that it has anything to do with his drinking. How would they know that?
