Getting drunk to cure the hangover for getting drunk the day before is an idea, the value of which decreases exponentially with age. And let's not kid ourselves about the "hair of the dog" deal; it just means, "Hell, I feel so bad that getting drunk again is my only option."

For instance, at 18, you may find that you can partake of the hair of the dog that bit you for up to 5 days in a row before you come crashing down to forced sobriety. At age 30, you may find that the number of days is down to 3. At 40, you will probably have decided that getting drunk is a stupid idea in the first place.

My advice would be to leave the cursed demon of drink alone if you find that you like to imbibe to the point of needing the hair of that damn dog.
