I had bladder surgery when I was little and...?

Now that I am older I pee over and over and over it never fills empty. The first time I go I go alot. Right after like 2 minutes after i go back and it's smaller like almost a tablespoon. and so on and so on like 4 times till I;'m fine. It acts up at nights mostly and right when I relax and go to sleep it gets that full filling. I also can't wake up ithout having to go. When I wake up I have to go bad. It's like the urge to go pee is always there. I made a doctors appointment but it's in a month. I'm trying to get some good advice on what might be wrong with me. Does anyone think I might have to have surgery again?
