When you wake up, the head aches because you are dehydrated and you've lost nutrients essential for your body. Avoiding caeffine helps, too... and replacing potassium. Eat a banana!
Here's a quick fix for all you party animals that just had to drink themselves to oblivion.
SLEEP: best cure folks; sleep it off
FRUIT JUICE and lots of WATER: you're dehydrated
BLOODY MARY: it has alcohol, but lots of goodies too (the hair that bit you)
3 oz tomato juice
1 dash lemon juice
1/2 tsp Worcestershire sauce
2 - 3 drops Tabasco® sauce
1 lime wedge
1 rib of celery
Ok, now, go back to sleep until Wednesday. Use this cure anytime you're going on a river trip and you did a bit too much the night before.
