I'd be interested to know if you find an answer to this one,
@Long Haul Mono. I have nights when I visit the toilet every half hour for the first half of the night. How I'd love to get an undisturbed night's sleep - as most of us would!
ME certainly throws up some challenges.
"...some challenges"
Now there's an understatement, but at the risk of going out on a tangent I'll spare you the details.
If you're not already doing so, try side-sleeping, or better still, front-sleeping, if you're able to.
For me, the worst of the nocturia happens when I'm sleeping on my back. With side-sleeping I was able to reduce the incidence of toilet breaks down to approx. 2-3 times a night. Sleeping on my back would be similar to what you mentioned, ie toilet breaks occurring every half-to-one hour.
(Specific to the male readers) it's worth ruling out prostate issues.
Other things to check:
Urinary tract infection.
Aldosterone levels.
Cortisol levels.
Calcium levels (I've heard hypercalcemia can result in excessive urination).
Basically everything that can go wrong in the pathway from the kidneys, down, including kidney function itself.
Also, take note of water intake (is it excessive?). Are you drinking too much coffee/tea?
To those reading who are new to ME/CFS, one of the key approaches to management is the process of elimination, ie rule out the simple/basic/typical stuff, and if possible treat it and move on to the next challenge... noting this is my personal opinion only.
You're dealing with a multi-dimensional syndrome, ie you may find you need to treat X, which will impact Y, which subsequently will help you manage Z, where there seems to be no remedy to treat Z directly.
One of the strangest symptoms I noticed personally is the effect cold temperatures have. Basically, if I'm cold I won't stop going to the toilet. Literally, I'll finish and approx. 15mins later, full bladder.
My GP has identified this as a serious yet unknown concern, ie my intolerance to cold. This is an ongoing (separate) "longer term project" to possibly relocate to a warmer climate. I've spoken about this in another thread, but now it's starting to look more-certain... It's a long story potentially for another post/thread.
I'm currently working on a running-hypothesis on how to deal with the creatinine, which I started 'experimenting with' yesterday. Last night I managed to get a 4hr stretch of sleep, so it looks promising, however in my experience, things are quite changeable from day to day, ie too soon to reach any conclusions.
If there are any noteworthy discoveries I'm considering starting a new post instead of continuing to diverge from this thread's topic. A lot has transpired, and some things continue as a work in progress, but the key challenge at the moment is managing this nocturia.
