Do you suddenly feel the urge to go to the bathroom as soon as you reach home?

This could be due to a brain conditioning phenomenon called latchkey incontinence. People often have to wait until they arrive home to relieve themselves. The brain might get used to this pattern and start associating arrival home with the need to urinate, triggering the urge whether your bladder is full or not. A strategy such as bladder training, which is useful in changing urination patterns, might help.
