... known him, almost 20 years. He's developed insomnia from meds he must take for a liver transplant he had 6 yrs ago. The Dr. put him on a sleeping pill and now he's like a burnt out addict. He falls down, can't talk conheriently, doesn't remember what he's done. And to beat all he is not getting any good sleep. It's almost like he's enjoying the state he's in. He's like a walking overdose. Can anyone explain his behavior to me?
