Does the stress level go down post-retirement or just change?

I'm retiring in about 7 months (wahoo!) just after I hit 59. Right now at work I'm working on/pushing some major strategic initiatives and training my protege to take over when I leave. It feels like I'm doubling up on the workload right now, which is leaving me very stressed.

I imagine what post-retirement life will be like, and part of that is my belief that my stress levels will go down significantly. I realize it varies from person to person...but did you find that your stress went down (eventually) after you retired? Or, were you just exchanging one set of stressors for another?
