Every day I get only 5 hours of sleep at night. What wakes me up is the need to pee. After that, I feel extremely tired but can't physically go back to sleep. I would end up taking afternoon naps but stopped doing that a few weeks ago, and that didn't cure my problem.
This all started happening one day when I took Benadryl to fall asleep earlier. That day I woke up after 5 hours of sleep and felt the need to urinate. Every day since then I have been waking up to pee and can't fall back asleep after only 5 hours of sleep. (I stopped taking Benadryl 2 months ago.)
I feel extremely fatigued and my brain cannot function during the day. Like I said, I try not to sleep in the afternoon, but the next night I would still end up getting only 5 hrs sleep.
This has been going on for 3 months now and I don't know what to do. Any advice?
Note: I drink coffee daily but have been doing so before this all started, so I don't think caffeine is the issue. I also don't drink much fluids before bedtime.
Could the benadryl have caused a disruption in my sleep-wake cycle?
