Caffeine tricks you into drinking more alochol. And, they e both diuretics and very dehydrating = more of ahangover.

• Depends on weight (less weight = higher BAC)
• Girls have less enzyme and less water to dilute
• Rate of absorbtion.  Faster you drink, faster the BAC goes up
• Eat before/after slows down
• HIgh conc = faster absorption 
• Heavy drinking (5 men, 4 women)
• Time is only way to sober up

• 0.04 should be below this for safer
• 0.05 harder for motor coordination judgement or memory may go
• 0.10 start to lose control of emotions, feel physically sick
• 0.15 BLACKOUT.  Memory isn't recorded
• 0.28 nerve control impaired.  gag reflex gone. HOSPITAL NEEDED.
• Alcohol is a drug.

Dehydration is main cause (alcohol alters activity in hypothalamus)

Liver breaks down alcohol into a toxin, which makes you feel sick.

Only cure is to wait it out. 

Alcohol enhances activity in nucleus accumbens (part of brain that feels pleasure)
