2. YOU’RE TIRED OR MOODY AFTER A NIGHT OF DRINKING
Got eight hours of rest but still woke up tired and groggy? If you drank the night before, that’s probably why. ‘Alcohol suppresses the REM cycle and results in poor sleep. That’s a big sign you’re drinking too much,’ says Dr. Hendricks. Hangovers don’t just come in the form of a pounding headache or queasy stomach; people who wake up feeling overly tired, anxious, sad, or irritable might actually be experiencing alcohol withdrawal symptoms, he says.
