Hydroxyzine dosing - How much would be too much?

[monstanoodle]

I know that Hydroxyzine is relatively non-toxic in large amounts, but I'd imagine it would still produce delirium in large enough doses.
I've taken 100mg over the space of... 8 or so hours. It's to combat Codeine itches and to be taken for Anxiety so I needn't take Diazepam every day.

So yes, I would like to know of the largest doses you've done or have read of (but please, no "my cock is bigger than your cock" rubbish - this is not my aim).

Thankyou

p.s. I've had a search but nothing significant came up.
p.p.s. Wow.. This must be my first thread I've made in months!

100mg every 8 hours is an ok dose (hydroxyzine half-life is 8 hours).

Too much depends on you tolerating the effects of said drug. A friend can take 400mg in one go without noticeable side-effects. I can't take more than 100mg a day.
But for the sake of your question, I'd say 300mg in one go is already too much...

Righto mate, cheers
I am quite tolerant to Antimuscarinic properties of substances, so that could help avoid some side effects. But yes, I think I'll stick to a maximum of 300mg a day in 100mg doses.
Thanks again Lou

Update:

I took around 200mg over the course of the day, prolly 100mg of that getting closer to bed (along with Codeine and Diazepam) and jeebus, did I experience some weird shit.
It was sort of being half-asleep-half-dreaming.

Things like I was in different rooms knockings things over or turning over in my sleep to switch something off but as soon as I noticed there were no sounds to accompany these "acts" I'd come too and be weirded out.

I've experienced similar things when nodding out on H with the aid of Diphenhydramine or Promethazine actually.
