Leveled up unintentionally

Hello, good people of Nostalrius! I have recently been enjoying War Song Gulch at level 29 so much with my character Morogamo that I wanted to stay at Level 29 for a few more weeks at least before I continue questing.
Recently I wandered into some unexplored area and "accidentally" got enough experience to get to Level 30 before I really intended to do so.
Is there any way I can be "bumped down" to Level 29 (removing experience, character rollback, whatever) just so I can continue playing WSG at Level 29 for a few more weeks and then go onto Level 30+ when I'm truly ready?
Thanks!
