How well do you sleep at night?

I used to nod off around 10 and mostly slept through the night unless it was my water pill day and sometimes it worked the best at night. Now, i have trouble falling asleep. Last night i finally dozed off and at 11:30 my door opened and the light went on and i heard you must get up and leave your room. This is a fire drill. I understand the importance but i sure didnt appreciate it last night. Then i had trouble falling back to sleep
