I Am On Two Medications Not At Same Time But

I am on two medications not at same time but trying myrtbetriq and oxybutin 15 mg and I do not see u h differ eve but have not been on the myrtbetriq for only about 6 weeks . I find myself hungry all the time and not sleeping well . I would rather have oxybutin with less chemicals if I am not getting a large benefit.
My biggest issue is sitting at a football game for grandkids and no bathroom round makes me very nervous.
Plus I had 5 major operations in Four years and cannot walk that well so running to the bathroom is not going
To happen plus I am 78.
What should I so
