Well a change in activity. Felt very weak in the morning, found my blood pressure had dropped. So went to one of the Urgent Care clinics. First one had a 2 - -3 hour wait so drove a mile to the next one and got taken straight in. Diagnosis is bronchitis. Extremely impressed with the service and staff. They phoned in a prescription for an anti biotic, did an INR on me and away we went - elapsed time 45 minutes maybe. Drove to Costco, but there would be a 3 to 4 hour wait for filling the prescription so we went home. M picked it up in the pm. The clinic phoned about the same time that M got back to say they had INR results and that was was in order at 2.8. Had a nice supper, read all evening until 10:30 when I finished the Grisham book. Slept good.
