Query: Minimal improvement at best

I did a lot of research on many different herbs and decided (based on the reviews) to give this a try. I was waking up at night and having urgency to go during the day. I've used this product now for a while and have seen minimal, if any benefit. No side effects but just hasn't done what I hoped it would do. I am going to try to increase the dosage but I don't think it's going to work.
