Over the last few months now I've been experiencing on going night time symptoms where I'll wake up anywhere from 130am - 530am sometimes with this slight feeling that I needed to pee. However I don't always end up actually peeing. The times I have been to pee during these early mornings I can void around 400/500ml so not an excessive amount. Around 6am I can fall asleep again for another couple of hours.
Last few nights I've woken up at like 2am after just one hour of sleep and can't get back to sleep, this is seriously frustrating. I'll wake up feeling like I've just slept 7-8 hours! And then the weird thing is, is that I hardly ever even feel tired throughout the rest of the day. Makes no sense. So during the day time and waking hours I'm fine.

I don't have any other symptoms apart from this slight need to pee (and as I said I don't end up peeing most of the time) but no pain anywhere etc.

I had a prostate/PSA test and that's all normal, urine culture/test came back normal too. Personal blood sugar monitoring was normal too and as far as I know I'm not diabetic.

I know there's something called middle of the night insomnia which can be very common. If I can get by then maybe there's nothing to worry about for now but in the long run this can't be good. Been happening for more than 3 months now anyway.
