Be careful with that stuff. Gatorade causes alcohol to be absorbed at a much faster rate because of the electrolytes binding with the alcohol and increasing the absorption rate. It can be a lethal combination if you drink too many too fast.
Contrary to popular opinion, the Gatorade does not help maintain electrolytes when drinking mixed cocktails with it and reduce side effects...in fact, it does the opposite. It will make the side effects worse.
Gatorade only helps after all the alcohol has been absorbed and processed by the liver and the body is needing to replenish the lost fluid and electrolytes.
