Erowid Diphenhydramine Dosage
I wouldn't go any higher than 1000mg. Really negative side effects start at like 250-300mg.
LD50 for rats is listed as 500mg/kg which figures to 40,000mg for an 80kg/175lb person, assuming the LD50 for people is the same as rats.
Highest I've done is 250mg and it was horrible. I've seen people take 1200mg and they weren't having any at all. Nasty stuff at high doses.
You should be okay with 300mg, I thought you were gunna shoot for 750mg+ or something.
After a period of abstaining from the oldschool antihistamines I would start with a lower dose (250-300mg?) and work your way up from there, ideally keeping those side effects to a minimum![]()
This is really better suited for BDD.
Hopefully you'll get some more helpful responses

Hey now, Cane, my responses aren't helpful?![]()
First of all, you need 650+ to get any hallucinations from this shit.
Second, PLEASE don't do DPH. I made the mistake of doing it once.....
It really depends on personal reaction, I had full-blown hallucinations at 250mg.
I wouldn't just be worried about the nausea aspects, but my muscles feel all sorts of somehow-tense-and-relaxed-at-the-same-time and the urinary retention but having to go take a piss every 2 minutes because you're chugging water because your mouth is so dry, belch.
I've done DPH at varying doses. How on earth do you guys stay awake long enough to hallucinate?
I just don't understand what goes through someone's head while they see these things. Do you just stare at these hallucinations and think "Well, ok. That's nice."
I really can't grasp the concept of flat-out seeing shit that isn't there.
