Not much sleep last night

I reported to the sleep clinic at 8:30 last night, filled out a bunch of paperwork, got wired up and went to bed at 9.  I think I finally went to sleep about 11:30.  Then, I woke up at 3:20 and never went back to sleep.  However, they said that they got enough data to complete the study.  Hopefully, it will lead to fixing the Afib and I won't have to break my streak with a pacemaker implant.  I was groggy all day today, but Mowed the grass and ran 2.5 miles on the trails at the park this afternoon.
