Leg cramps can be fun, but not when trying to sleep. I had some problems with those night cramps when starting spiro - one night I couldn’t just walk it out, so I had to drink water if I wanted to sleep (I did try to sleep while just ignoring the cramp, but that wasn’t successful). Made me kinda glad my brain often seems to discards pain signals. Fortunately, haven’t had night cramps in the last few months.
If I don’t already have water, it’s annoying having to find my cup (which might require turning on a light), go to the kitchen to refill (which requires dealing with the fridge light), and then try to fall back asleep after that. I’m generally not good at falling asleep, so if I can avoid getting up or turning on lights, the better chance of falling back asleep quickly. Getting up like that might cost hours of sleep time.
