Should I be on my way to the hospital?

[elgnidead]

Hi everyone,
I'm new to this forum.
The main reason for joining was for this one question, but i'll definatly be visiting regardless.
Anyway!
Oxycontin.
I've been doing oxy for a few months now.
I've gained a pretty big tolerance, but last night, I took 320 mgs. I snorted a bunch and took a bunch orally.
Anyway, i was feeling it to say the least...but i started feeling really odd, so like the idiot that i am, i think, i'l sleep it off.
i woke up at 9:30 (after going to bed at 6) and when i woke up i was still feeling it very badly, i've randomly passed out a few times for a few minutes at a time, i puked a few times, and im really having a hard time talking and doing some simple tasks.
I searched the internet looking for like an LD50 of oxycontin or something.
I couldn't find anything about leathal doses and I understand that it has a good bit to do with tolerance, but just because i'm alive doesn't necessarily mean i'm not word about something happening to me.
so therein lies the question.
Is there a LD50 for oxycontin?
Should I possibly go to a hospital or something?
Any extra advice?
I'm just worried about myself. Sorry if this is kind of long and sorry if you are reading this thinking "why'd i waste my time on this retard?"
But if you can help, i'd love whatever i could get.
Thanks a ton
