Is the past going to hurt my chances???

I am 28 and going back to school to become a nurse. I was in rehab as an adolescent at 17 and then again at 19. I checked myself in at 19 to a rehab center. I have been a regular member of AA and sober even since January of 99. I was addicted to opiates and alcohol but never used an I/V drugs.

I got my life together and have been in the computer industry ever since with a stable work history. Now I want to help people as a nurse.

I feel I have proved myself with about 9yrs of recovery behind me.

Will my past be an issue? What things might I have to do in order to be a nurse that others might now have to do? Would I have extra restrictions or would employers be scared to hire me?

I would of course be honest...just hoping the mistakes I made do not haunt me. I feel with all I went through I gained a new sense of compassion and want to share that.

Thanks
Jeremy
