The are a few options depending if you have someone to help you or not. You should try to end up next to the barrel closest to the board when you become superdrunk. If you lose your superdrunk status you only have to use the barrels once to become superdrunk again.
If you are solo the best bet is to just map click or click on screen and let your character attempt to run there. Trying to use the arrow keys takes much longer. Once you do use the nails you can logout and wait for them to reset (about (which takes 30 seconds) and login again and use them right away.
If there is someone else there to help you can have them push you to the board. When another player pushes your character it will not be affected by the superdrunk condition causing you to go in the wrong direction.
