Would taking 1000mg of Diphenhydramine Hydrochloride and combining

Well the LD50 is 500mg/kg in rats.
Typpically the bigger animals are the less mg/kg is needed for a deadly dose and when they are non- rodents they are more sensitive towards substances too.
That trend is shown in that for dogs on the other hand the LD50 is just ~25mg/kg.
To kill a 70kg human in HALF of all cases the LD/50 must be <15mg/kg.
The other than with paracetamol the alcohol is largely irrelevant with this, it will "only" hinder eleminating the substance from the body, meaning its full dose will last longer.
It surely CAN bring you on the edge of death and definitely into the emergency room at your hospital, but you cannot guarantee it.
->1000mg is too little
The character will be high as BALLS though, holy shit, 200+mg are said to be enough to induce hallucinations...

Ok, I'll try writing 2000mg then, bearing in mind the character in question is 5 foot and around 100lbs - surely that will lower the required lethal dose?

With 45kg and 2000mg the Ld50 for humans would have to be <44 mg/kg
Sounds plausible deadly.I think no reader will doubt the deadly effect of that much of such a potent psychoactive substance.

Yeah, then you wake up the next day feeling like shit and wondering why you didn't have the guts to end it properly.
