If you broke up on good terms, stay away from each other for about a month or more. Relapsing back into the relationship can be fatal.
Same goes with other women, don't get into a rebound relationship. I had a rebounder last for 7 months and ended up in a REALLY REALLY messy breakup. Not cool.
Go out with your buddies and drink and go to a strip club. You'll feel worlds better.
But like Azraele said, don't seek solace in alcohol. I just find it incredibly fun to get sh!tfaced.
