Diphenhydramine is an antihistamine and will not kill you. 99% of people who attempt to OD on sleeping pills just end up sleeping for a long time and/or going to the hospital very sick. I know you're desperate but this is very unlikely to work.

If you do some research I'm sure you will find a concrete answer.
