On Sunday, I did an amazing out of walking, and yesterday I had to go get medicine and go by my primary doctor's office to reschedule two appointments in early September, so I did about the same amount of walking, yesterday.
Today and Thursday I have PT pool therapy sessions....which after I'm done, I usually need an extra pill to relax my muscles and body (it's non-habit forming, and it works well to help ease my pain levels).
Friday I go to my monthly doctor appt to evaluate my ongoing medical condition. My doctor may recommend other forms of water therapy to go with the current model in use.
All that to say, that by the time I'm done with necessary walking, either for enjoyment or for medical treatment purposes, I'm very tired and ready for a big nap or to rest primarily in bed, for a good while.
