Subject: FATIGUE, OLD AGE, NIGHT PERSON
I am fatigued early, late, and often. And if I go out during the day, I doze
off during wonderful TV. Most of my life I have a been a night person, but
teaching school made me an early person. Had to. In self defense. More and
more fatigue led me to diagnosis of PPS (eventually!), so I quit teaching,
slept and continued to be a morning person. That was 5 1/2 years ago. Now I
sleep several hours at a time, but rarely more than 4 or five. I wake, play
with the computer, read, eat, and generally wander around the house. Then
back to bed for a few hours. I go to bed sometimes late at night (3 a.m.),
sometimes earlier (11 p.m.) But no matter. I am almost always living in a
perpetual state of tiredness.
I am 66, formerly quite active in work, community, family, etc. (Weren't we
all?) Now I am quite content to mostly stay at home, listen to my Library of
Congress tapes (Thank God for them!) and generally live a quiet, calm life.
And I love it.
But I do not.. ..repeat NOT . . . believe my excessive fatigue is due to
aging, but is due to PPS. Of course, I have the attendant physical problems
that settle on humans who live long enough, but I do not believe any of them
causes fatigue, either.
I do notice that when I am excessively tired, or just a little overtired, my
mind doesn't work as it once did. I sometimes have something explained to
me, understand it perfectly, forget it and then find a second explanation
bso
lutely incomprehensible. I tell my roommate that "my mind has clicked off
again" and bless her, she understands.
My mind also works more slowly and some things that a few years ago would
have been obvious to me now seem to be less so. Thanks to this list, I now
know I am not alone.
However, when I am NOT tired, or if I am excited, then things are almost as
good as they once were. So I try to stay un-tired. I find this hard to do,
of course. But I am getting better at it. All in all, the good hours far
exceed the slow ones; life continues to be rich and people continue to be
wonderful. In different ways, though.

Subject: Sleep Patterns rather than sleep quanity
As PPS begins to effect my daily life more, I have noticed that I do need
several naps, but the total amount of sleep required in a 24 hour period
has not really changed. A 30 min nap ( OK sometimes 60) in mid-morning
and then at least 30 more min around 4pm seems to work for me. With that,
I can get up with the family at 7am, but I am not ready for bed until
after 1am.
When I worked a "regular working day" with the Veterans Administration, I
would normally get up around 7:30 or so and be in bed bed no later than
midnight..
I have also noticed that with my new sleep schedule, the wandering aches
and pains that always followed aggressive physical activity have not been
as pronounced. I am admittly "underemployed, and hope to go back into the
office again someday, which means finding a way to accomodate the naps.
It appears that I will lose weight as I sleep everyday through Lunch, and
will look like a "typical government employee" because I will leave
promptly at quiting time for the afternoon nap...But so be it.
