In small amounts, alcohol acts as a stimulant, a relaxant and has the potential to lower one’s inhibitions.When consumed in large amounts, alcohol can distort the mind, slur speech and slow responsiveness, as well as cause movement and balance problems. The ability to assess risks and make conscious decisions is also impaired.
If you drink too much, alcohol causes nausea and vomiting, cramps and unconsciousness. Potential long-term effects include severe liver damage (cirrhosis of the liver), nerve damage and psychological problems such as depression or hallucinations. There is also a danger of developing a physical or psychological addiction.
