I would recommend appealling it instead of waiting a year to re-apply. I had two dui's one form 2001 and one from 2008 both were misdemeanors. My timeline was the following:
Graduated from school September 2010
Passed NCLEX January 2011
Denied License March 2011
Wrote to the board that I wanted to appeal April 2011
Received Hearing date December 2011 (for July 2012)
Hired an attorney (January 2012)
Settled and was approved on probationary license (June 2012)
If you wait a year and then get denied again, that will put your wait time that much longer. If you only have one DUI and it was a misdemeanor that is all that was on your record, I am surprised you were denied? There were a few people in my class who had one dui and they were approved. I am so sorry you are having to go through this, I hope you will make the right decision, I know how hard and frustrating it can be. Believe me I lived it and I still feel like I need to pinch myself that this is over now. But I did not give up and I had faith that I knew that I had worked to hard and my dream was to become a nurse and I was not going to let anything get in my way. I was completely fine with the probation license, it was my fault for getting the 2 dui's in my past so I need to prove to them that will never happen again I will do whatever it is that ask me to do. Anyway, best of luck to you, there is a light at the end of the tunnel. I would suggest if you do appeal, hire an attorney asap, maybe they can speed up the process also it helps with peace and mind as well.
