How many milligrams does it take to cause full blown open eye hallucinations?

depends on the person.

erowid.org

already looked it up. couldnt find anything on how much you need to take to achieve open eyes hallucinations. I took 700 mgs about 45 minutes ago.

300 to 500 milligrams for most people. Do it at night outside and you'll see some very unique kinds of hallucinations.

Or you could just take some acid.

Those hallucinations will start soon enough.

ive always hated diphen.....how it dosnt suck 4 u, it always ends up makin my knees HURT like hell......worse then when i got my root canal.......

is there a difference between dyphenhyramine & diphenhydramine?

Haha Diphen blows.

It's like a high with no euphoria, so not really a high.

Plus, It's scary as fuck seeing tarantulas everywhere..

Yes. The former is misspelled.

Just woke up after last nights trip. Wasnt really what I expected at all. Slight hallucinations, I was looking at my friends posters on his walls and they would blink and move their heads. When I closed my eyes I would go into other rooms in my mind and talk to people. Overall, I didnt hate it. But I didnt exactly enjoy it.

Exactly.

I mean, I guess if you can't stand to feel normal it's okay, but being unable to sleep with a shitty body high, and every couple minutes tripping out and opening your eyes to see a tarantula or something on your wall for like 3 seconds sucks dick.

However, I really like taking like 150 mg for sleep, smoke a little weed and it knocks me out cold, I love it..

This man speaks the truth, the worst part about it was the restless legs UGH

I don't think its bad, i actually kind of like it. Just don't take to much. IMO 350-400 mg is a good dose to get some interesting visuals, just take like 2 or 3 caffeine pills the same time you take them, then you don't feel all tired and shitty, you just feel super relaxed. I always seem to lose depth perception when I take it. Like i will try to grab my mouse, but it is like 6 inches farther away then i thought it was. And i was walking around outside my house one time, and shadows looked 3D like they were actually the objects they were the shadows of...all in all not a bad time. But then i went back inside and started talking to people that weren't there...thats really weird...

i love diphenhydramine, it fucks you up, after 12 pills your talking to a brick wall for the next 4 hours and cant walk because u think your muscles have atrophied, i only know of OTC packet it comes in down under and it aint cheap, who knows ways of getting it cheap in aus

Do it! not too much though, just have a nice sampling.
The weirdest thing I've done on it is walk outside, then look at my house and it looks like someone elses. Next I look at the yard and see my mom and a friend talking, I say hey and they looked at me. Of course I was just fucking hallucinating them, so I walked to the side and just stared at the house paneling. It's weird, but if you have no drugs then it's something to waste time on.

This. Happened to me before, but it was just two bigass white spiders that crawled in under my door.

Yeh, I actually accidentally went up to my neighbor's house thinking it was mine, when I was walking home from the store nearby, so I just asked them for a cigarette and left. xD I was fucking out of it. Diph sucks, but it gave me some weird experiences back in the day.

This is pretty much it. It's not bad, but I've never actually gotten visuals, but I can vouch for the depth perception.
