Yes, or very little. However, there are periods of time when everything functions as it should- some days I can go 5 or more hours without issues of any kind. By that, I mean that I don't even have to void; when I do get the urge, I can make it to the bathroom and all goes as it should. After that, anything can happen- another several hours of normal urinary functioning, or the close calls can start; as well, it can be a minute after voiding that I have to empty my bladder again and it can be a large amount or a very small amount- it's very unpredictable. I should say, though, that in my case, the cause has been diagnosed as a head injury I had in 1988 and other symptoms, whether they be memory, or vision, headache, vertigo, (or any one of a number of other issues) are the same- very unpredictable. Oab may be different for others suffering from it.
