What's that? I don't believe in something with no cause. And overactive bladder has no cause. But I think there must be some bacteria and bladder is lucky to be able to get rid of bacteria in natural path. So the more often and the more urgent urination is the more bacteria are there and the bladder wants to get rid of it the soonest so a few meters are sometimes too far.
Maybe 5 years ago I went to the spa and as I was afraid of disaster I drank very little while traveling. The next morning at the standard test they found plenty of bacteria in my urine. I was ordered to drink much water to splash it out. And in 3 days my urine was clear with no bacteria but there was usual urgency. While I didn't drink there were no urgency and bacteria stayed in my bladder. After coming home from the spa the first way was to my GP and asked for the test of urine. Surprisingly it was again clear.
Now I got angry with my "overactive bladder" and decided to defeat it. So I am going to order cranberry in the mixture with D-Mannose and I hope it will be better. I don't know why I haven't ordered it sooner.
What I have noticed after increasing abxi  or during and after pulses it gets always worse. As if abxi  help to kick bacteria out of the bladder. And the urgency also gets worse. I hate it so much. I stay at home only because of this problem If it weren't for this problem I would go for a walk or to the supermarket or wherever.
5 days ago I started to take roxi in one dose. There where much reactions (in my head, legs, difficulty with breathing) in the first days but now I think I am better. As if my legs felt stronger, I can stand up fast and usually without support of my hands (my hands are only in alert if something...), I can do usual work with almost no effort and I can even do more work. These days and the next month we are having stressful work in my family -reconstruction of a flat. Everybody works hard to arrange something and I do either. Arranging things on phone and there is nobody to help me at home so I have to manage everything by myself and I really do. Sometimes there is more mess in my flat but I don't care about it I say to myself I will do it tomorrow and I really do it with no effort. Only my bladder makes angry me. When I move, walk, bend, lift something there is always terrible urgency. So when I go past toilet I always enter it, bu often nothing. So I go out and after 1-2 steps there is again terrible urgency that sometimes way back is too long . When it stops? I hope cranberry will help.
