Excellent thread. I've developed the worst sleep patterns-I sleep an hour or two, wake for a couple, back to bed for a couple, up for a couple.
Nocturia is a problem. I'll be deeply asleep and then I have to get up and go. By the time I stumble back to bed, I'm often quite thirsty and can't sleep if I don't take a drink, but if I do, it wakes me up.
I also have RLS -- restless leg syndrome and leg/foot cramps that keep me awake some nights. Depends on how much I've been on my feet all day. Sometimes I'll take a few Advil to get rid of the pain and that works pretty well. I've tried drinking lots of water, taking K+, and various other remedies, but the only time I have the problem is when I've been on my feet a lot, and the only thing that seems to work for me is Ibuprofen.
It's rare that I can just get into bed and sleep for a few hours straight. If I get 6 hours at one stretch, I'm ecstatic.
I seem to do best if I have the TV on a channel that doesn't have commercials because the change from the program sound level to the louder commercial will jolt me awake. I'll sleep a couple of hours on the recliner, then get into bed for a few. My family is used to it at this point, but I envy those who can just have a real sleep all night with their spouses.
I've finally gotten to the point that if I don't sleep, I figure it's because my body isn't tired, so I might as well take advantage of the solitude in the wee hours.
When I'm awake and everyone else is asleep, I can get some housework or laundry done, catch up on the bills, take a shower, study, get on AN and do my thing here or play online games with the Australians & English (who whup my butt every doggoned time, BTW

). Sometimes I'll go out and do some shopping at the all-night superstore.
Benadryl turns me into Mr. Hyde. I had no idea how horrible I can behave until I tried that awful stuff. Makes me feel drunk and hung over. I really don't care if I say something that hurts someone's feelings, I just get all sarcastic and mean on the stuff, so I'm afraid to take any medication to help me sleep.
It's true, I hate going in to work on 4 hours of sleep, but we've recently gone to having set days off so I count the days till I can just stay home and catch up on my sleep. Which is what I did all day today.
So I guess this is just a vent, because I've pretty much come to accept that this is how it's gonna be.
I try to be nice to my family when I'm awake, because when I think about the future, I believe that my caregivers will be in for a rough time when I'm an old demented lady.
