Hi again Roy.
Getting up at night frequently to urinate is called nocturia. I often have to get up for a pee, two or times a night. It's annoying and can lead to fatigue caused by disturbed sleep. I often feel extremely tired in the late afternoon.
There can be many causes, including medications, urinary infections, prostate conditions and old age. If it's causing you problems I suggest calling you GP mate.
Good luck and I hope it eases.👍
