The most obvious and immediate effects of alcohol are on the brain, beginning with feelings of relaxation, wellbeing and loss of inhibitions. However, as the intake of alcohol increases, these effects are counter-balanced by less pleasant effects, such as drowsiness, loss of balance, nausea and vomiting.

Alcohol slows down the messages sent between the brain and the rest of the body. This can make you:

  • relax, feel good
  • do or say things you normally wouldn’t
  • feel dizzy, have bad balance
  • have trouble controlling how you move (bad coordination)
  • react slowly
  • get angry
  • vomit
  • have blurred vision (not see clearly)
  • slur your words (not speak clearly).

Drinking a lot in a short time can cause:

  • a hangover
  • headaches
  • nausea or vomiting
  • shakiness
  • passing out
  • stopping breathing (rare).
