yes, I too have this problem.....very annoying. I notice it gets much worse about 12 days before my period. I feel like I need to urinate all night, it becomes very hard to fall asleep, and when I finally do, I end up waking up a few hrs. later with the feeling like I have to go again. Sometimes I really do have to go, and other times, it's just a strong feeling with very little urine - I don't know what the heck that is, but boy, it is really annoying! I feel o.k. otherwise, no fever, or sickness to speak of......just that nagging feeling. My friend also has the same problem, but her GYN said it was her age (same age as myself, 45) and menopause or something.....I've never heard of that happening! well, if anyone knows about this, please post!
