Well, you're squeezing, but other than that, no. From SRD:

"In some cases, you may have to squeeze into or through an area that isn’t as wide as the space you take up. You can squeeze through or into a space that is at least half as wide as your normal space. Each move into or through a narrow space counts as if it were 2 squares, and while squeezed in a narrow space you take a -4 penalty on attack rolls and a -4 penalty to AC."

Duration is for one full round. You will act again in one full round from this action, immediately before Krull. On your next action, you lose the DR. However, you will have it for the duration of your opponent's current turn.
