insomnia
"I take diphenhydramine in Ibuprofen PM to help me sleep, though I only take one pill and not more often than every third or fourth night. It works like a charm, enabling me to sleep without needing to get up and pee or waking up with my life concerns preventing a return to sleep, for 6-7 hours.
My concern is whether it is habit-forming, whether taking this drug for sleep on some nights increases the difficulty I have in falling asleep without the drug, on other nights."
