Final answer:
Increased energy is not a key sign of alcohol overdose; confusion, slow breathing, and unconsciousness are the key signs.
Step-by-step explanation:
The key signs of an alcohol overdose (alcohol poisoning) include confusion, slow breathing, and unconsciousness. However, increased energy is not a typical sign of alcohol overdose.
Alcohol is a depressant that generally results in sedation and decreased alertness. Excessive alcohol use can lead to a loss of consciousness and difficulty remembering events that occurred during intoxication. It is important to seek medical attention if someone exhibits signs of alcohol overdose.
