I been urinating the bed for the past 4 nights without any notice until no wake up?

Your condition is called secondary enuresis. You should see your family doctor. A detailed history (including med review) and physical examination (including blood and radiology tests) are required for the correct diagnosis and treatment.

There can be many reasons. Stop tea, coffee alcohol after 5pm. Set an alarm to wake up and urinate one hour pror to the time this happens and empty your bladder. Try this for a couple of weeks. If not improved pl see a Urologist. Good luck.
