I am with someone that is lethargic, slurred speech, extremely tired, eyes are distant and not fully coherent. He s a male, 49 years old and has experienced this issue many times. He seems as if he s drunk but says he hasn t had a drink. He doesn t take drugs either. He had trouble making it up the stairs, tripping and not able to stand up straight when he tried to go to the bathroom. He has been depressed and has anxiety. But these episodes happen once and a while and then he conks out for the night. It has even happened during the middle of the day and he will just sleep for hours.
