Though many urban legends have been spread around possible hangover cures, the Forget Hangovers patch is among the most easy approaches to keeping terrible side effects at bay.
Designed to help ease the morning after effects of a night drinking, the patch releases low levels of thiamin into the blood stream. Thiamin is an essential B-vitamin that alcohol depletes, which in turn gives you a hangover the next day. Forget Hangovers says that by applying the patch before your first drink, you'll have a steady supply of thiamin and "prevent the hangover before it begins."
The patches come in packs of 10 or more and equal out to $2 each. Looking to try one out? Remember to drink responsibly and that while the patch may help with the morning after, it doesn't mean you can increase your usual limit.
