You see the way I understand an overdose is taking too much of a drug, that doesn't mean it has to kill you to be an over dose, but that doesn't mean its healthy either.
TRUE OVERDOSE:
what drug did you OD on?
DXM & Gravol (3 regular size bottles and 15 pill of Gravol at least in the same swallow)
what does it feel like?
I was with a friend and don't remeber shit (we were both high) I can't remeber ANYTHING regarding the ride to the hospital, fighting the nurses or the nurses lossing a needle inside my arm for a little bit

I had no feel of pain, or senses. Beyond delirum, horrible!
when you come to, do you remember anything?
When i woke up on the hospital bed i thuoght my mom was my friend and convinced i was in the basement (where we had started dosing). Took me 48hrs+ to sleep and about 3-4 days to recover. The doctors said my heart rate was through the roof and that I would have died of a heart attack. Horrible!
TOO MUCH OVERDOSE:
what drug did you OD on?
Narcotics, by themselves mabye just in combination with cannabis. None of which were smoked fentanyl nor oral fentanyl may I add that because I bet thats what all you were thinking. It happend from way too much oxycodone actually.
what does it feel like?
Like a panick attack, sort of with a lot of dizziness and shallow breathing.
when you come to, do you remember anything?
I came to after I decided to make myself a huge coffee (I don't drink coffee), and a half pack of cigarettes (I also didn't smoke much back then) and a LONG walk. A walk that would have taken 20-30min at most took me about 1hr-1.5hrs. Felt sober with an opiod afterglow.
what drug did you OD on?
MDMA- once unexperienced with 5-6 pills (clean and strong) during 1hr-2hrs at most, another time experienced with 20-22 130mg-140mg white omegas (best pills in the world) over 38hr-48hrs at most
what does it feel like?
unexperienced- (had all 5-6 pills within 1hr maximum 1.5-2hr period- it feels very disorienting, a LOT of throwing up and feeling like you need air, extreme body changes...mentally not too hard
experienced- (had 20-22 pills of 130mg-140mg mdma white omegas during the course of about 38-48hrs at most, cocaine (pure however 90%+) and a bit of cannabis & hashish as well as alcohol, though this was by say 38hrs-48hrs), however this coke just got us euphoric and more sober than we would have been without it. No throwing up just hallucinating and not being able to make sense for pretty much the entire 0hr-48hr period except with my buddy and even that was hard and difficult. (again coca made us more sober until we started vaporizing coca and got retarded around 28hr-43hr period, after that we split), Hallucinations were like that of 15mg or so of 2c-i and at times delirium like states. My friend was even higher than I was and at points in the roll/trip I got very concerned for him. He was making no sense in conversations (which has happened before on MDMA) but this time he was confident and believing in them, as well he was hallucinating pretty badly (worse than me), and believing in those hallucinations. Feels disorienting as fuck I'd say and feeling like your sinking into delirium.
when you come to, do you remember anything?
unexperienced- Of course.....just didn't think about the stress I was putting others under (they were glad I was fine though).
experienced- I had a good memory this time too though I found that I had to pick up alot of pieces of the puzzle from that roll/trip. I went home like I said after we had a few hits over 3hrs-4hrs of vaporized 90%+ coca and ended the session with a hash & weed joint/pipe. I was found in my room (my room was locked), someone was knocking on my window for hrs then the door for hrs then came in, apparently they had to wipe the drool from me and I was still in my jacket with hash and marijuana bits around me on the bed. After 2-3 days and re-confirmation from the friend I was tripping/rolling with we put the pieces of the puzzle together though not entirely. It was also a dangerous trip/roll since we got very high and took the car out while my friends eyes were rolling in the back of his head....needles to say we barely avoided crashing by 1 or mabye 2 seconds.
