This happens to me as well everytime i stand up.. If i sit back down I am generally ok... Agree that it is so annoying. You feel like you have a full bladder ready to give way, and then you sit down and *tinkle *tinkle... Super annoying.. cant imagine this getting any better over the next 9 weeks either.
This just happened to me for the first time today. I felt like i really had to go so I went to the restroom before I even left the bank. I felt like I had a really full bladder but when the time came there was only a trickle! I thought it was a one time thing! Thanks to this post I'll know to expect it again.
