I was taking ripped fuels and hitting the clubs, but it got me to dehydrated and would get off the dance floors dripping like I just got off the treadmill. Taken NYC's before workouts and I would imagine the effect would be the same.
As far as a cure for a hangover, I was coming back from Cancun from a few days of partying and had a delay hangover. It all hit me in the airport. These ladies that came over on the same chartered flight helped me out with some B12 that all but cured it. It was kind of funny taking some pink pills in a mexican airport. Could of been a tab for all I knew, hell I thought cool freebie.
