I take 3 benadryl every night to fall asleep
Why do you take so much medicine to fall asleep?
I have trouble falling asleep without it.
You should not self-prescribe medication and use it inappropriately. Benadryl is an allergy drug and is not meant to be taken consistenly. If you continue, you can cause yourself to have liver damage.
It's not a big deal, no one really knows but me.
It doesn't matter if no one else knows. You're the one who will suffer the side effects of taking so much medicine. Have you tried other methods to help you sleep like exercising more or maybe some relaxing music?
