Would 250mg Benadryl and 9mg melatonin be harmful

I've taken 10, 25mg benadryl allergy along with 3, 3mg melatonin. i weigh 195 and i often take other sleep aids in high amounts. Is this too much?

you know it is or you wouldnt be asking.... any drug where you exceed the max dosage can be toxic. you have taken 5x the max daily dose of benadryl and 3x the dose of melatonin... it doesnt matter how big you are you will still destroy your liver / risk killing yourself.
I seriously suggest you see a dr for some bloods to be taken and advice and start taking responsibility for your actions. Maybe you ought to be tackling the cause of insomnia rather than the symptom
