Before pd when I did something which took great effort, I would be tired, but it was a good tired. Now when exert myself (yesterday I drove 140 miles round trip to a nearby city) I am exhausted afterwards. Nearly anything can exhaust me. I am tired (not sleepy) nearly all the time. I understand that tiredness goes hand and hand with pd, but this seems like a sudden drop after an activity. don't forget how to laugh (and do it often) Marling McReynolds [log in to unmask] http://members.tripod.com/~marling
