Dextromethorphan has no effect on me (350mg). How much more should I take?

This has to do with robotripping, which im sure a lot of you look down upon..please move along if you do.

So i wanted to try to robo trip tonight because im in a new area so I can't find many drugs. When I was younger and (even) dumber, I took CCC's..on two occasions, with friends. Both times i definitely felt something, but not as much as my friends who seemed to be out of their minds. Fast forward to tonight...I downed a 4 oz bottle of adult robotussin(354mg DXM). Its been almost 2 hours and i feel absolutely no effects, the most i have felt was a slight stomach ache 30 minutes after drinking. I'm kind of pissed. Is it possible that i just have a tolerance to DXM? Does anyone know what could be going on?

There's nothing wrong with dissociative drugs like dextromethorphan or ketamine and I don't think it is looked down on that often around here. They personally aren't my cup of tea so I don't have that much experience but I checked erowid and found the following.

Oral DXM Dosages
Threshold unknown
Light 100 - 200 mg
Common 200 - 400 mg
Strong 300 - 600 mg
Heavy 600 - 1500 mg
Risk of Death 2,500 - 20,000 mg

I remember DXM is metabolized by CYP2D6 into an inactive and has an active metabolite which contributes to the effects (maybe even most), so you could just have an over active enzyme.

It could also be a natural tolerance (more likely with it not working when you were younger as well), something to do with absorption after meals, properly noticing the high, or the moon incorrectly aligning with Venus. Basically we don't know why you didn't feel it like you wanted and there is no use speculating.

Along those lines I'm going to close this thread now but you can looking into taking more or trying to mess around with your liver enzymes. Stay safe though.

Feel free to PM me with any questions or concerns.

p.s.
This type of question would belong in the Basic Drug Discussion Forum (BDD).

... do you think it would be a wise choice to try to double my dosage or maybe triple it? I felt nothing from 350mg whhich most people say is a pretty decent dose. Or do you think this would be a waste of time, money and effort?
Thanks.

The OP sent me this and I thought I'd open it back up and send it over to BDD.

OD >>> BDD

OP As I said via PM doubling it or tripling it could be a bit of overkill. I'd say go up by 100mg maybe and see what's what. That way if it was some other factors were at play you won't go overboard.
