Switching From Creative to Survival?

[Sean_]

I recently started a new Hexxit world, And I've been playing around with the items and such.  I switched to Creative, but now having trouble going back into Survival.  I don't see any button that switches me back to Survival.  /gamemode 0 doesn't seem to work.  When I go through Nether Portal, or Exit and come back in, I'm back in Creative Mode.  How do I properly switch back?
