I am an old man and suffer from frequent nocturnal urination,can anybody suggest a solution ? ;D

Medical questions should only be addressed by legally qualified medical practitioners.

You follow answers here to your medical problems at your own peril.

Frequent urination could be due to any number of medical conditions.

If you are over 45, you can be susceptible to diabetes. If your blood sugars are too high and you have a frequent thirst and/or are feeling tired, I suggest you visit a doctor in person as soon as possible.

You said you were an old man. Not sure how old you are but any signs like that should be called to the attention of a Doctor.
