My frequent urge to urinate in the early hours recurred after stopping natural medicines. Please help.

Hi doctor,

I am 36 years old and currently not taking any medication. I have occasional urinal issues. In the middle of last year, a few nights between 4 AM and 6 AM, I feel the urge to urinate even though I stop drinking water at least two to three hours before bed around midnight, and also I go to the toilet just before bed. I sometimes feel that the bladder is not entirely emptied (I guess it is called incontinence). I urinate four to five times a day until going to bed (and usually drink one to one and a half liters of water daily). I have taken some natural medication (plant-based) in the past, and the symptoms subsided, but once I have stopped it for more than one to two months, they came back. The prostate does not hurt, but I certainly feel a slight discomfort but nothing painful that requires attention. The pressure of the urine coming out is generally fine, with some minor decrease. It is annoying to wake up in the middle of the night or early morning to urinate. Should I go back to the plant-based prostate treatment? What do you think about Bangshil, and how should I take it if so? Thank you.
