By 3:00 yesterday afternoon - after the stress of the lobby stairs, two Access-a-Ride vehicles that forced more exertion than I'd like to enter/exit, and the schlep around my HMO - my legs were finished for the day. By the time I finished my late afternoon cleanup, I was crawling around the apartment. As soon as I lay down, I took three gabapentin for the pains. Around 8:30, I went to bed and set the alarm for 6:00.
