I Take Myrbetriq 50 Mg A Day And Have For

I take myrbetriq 50 mg a day and have for about 3 - 4 years. I am experiencing multiple times during the night that I have to get up and go to the bathroom to urinate. Last night it was 5 times. I have restricted fluids after 7:00 pm but it is not working. Would it help me to take the myrbetriq at bedtime or earlier ..... maybe 6 - 7:00. or should I ask my physician about taking a larger dose. Thank you for your advice. I sincerely appreciate it.
