TIFU by taking a lot of drugs

First post here so let me know if I ruined anything

Like so many other posts this happened 4-5 years ago but I didn't know about this place until later plus I was probably too paranoid back then to post about it anyways,

So this story takes place way back during my high school days when all me and my friends ever really did was smoke weed and chill. My parents weren't home that day and my friend came over so with the house to ourselves all we wanted to do was of course smoke a lot of weed. However it had been a pretty dry week and we were both out of weed at the time. Well my friend had recently been hospitalized and was prescribed large, horse-pill looking, Oxycontin pills. Now these pills were sold in the area and were apparently abused often for a quick high so without doing any research (FUCK UP #1) I decided hell yeah lets take some! My friend wisely suggested that we cut one pill in half given that these pills are large as is so we both took a half and proceeded to play some video games.

After a round or two I wasn't feeling anything so I got mad and decided to take another (FUCK UP #2) cutting another pill in half and taking one half, soon after I followed it with the other half and even later I took a whole pill as well (FUCK UP #3-5). I still didn't really feel anything but before I could follow with anymore fuck ups my little brother came with a bag a weed and announced it was timed to get fucking stoned.

We Had a gravity bong set up in this shed out in our backyard so the three of us headed out there to make proper use of this weed. Once we set it up I got greens (For anyone unaware what this means it means you get the first hit which is the strongest hit). and as soon as I lifted my head up after taking a heavy first hit my whole world just...melted. Vision was getting blurry I was out of it as fuck and I had cotton mouth like crazy so I mumbled something about going to get water and stumbled out of the shed to head back home. This is where it really went south fast. As I was walking my whole vision was going super tunnel vision and it looked like the path to my house was going away from me till I realized my whole vision was fading away as my vision finally cloud in on me I realized I must have tripped or something because I was laying face first on the ground with my vision still gone. Thus I began to freak the fuck out. I started yelling to the other two to come help me that I was blind and I couldn't move and I could hear them saying things like "He's just pulling our legs" or "dude is so stoned!" when finally I heard my friend come out and ask me if I was ok, that was when I started to lose consciousness, I awoke some time after to find I still couldn't really see or move much but I guess they managed to move me because I recognized the feeling of my couch, I heard one of them say they were leaving the house to get food and to just stay put before I drifted back off again.

I awoke again some unknown time later with blurry vision but enough to barely see, I was ecstatic enough by just this because in my fucked up state I had convinced myself I would be blind for the rest of my life. The reason I had woken up was the alarm clock in my sisters room was going off and It was annoying as shit so after a few minutes of what felt like I was straight out of kill bill forcing my body to waken I started to stag towards her room to shut it off. I managed to reach the doorway before what felt like my chest suddenly getting turned to stone and my heartbeat stopping happened and my consciousness went away again as I started to fall to the ground.

Little happened past this a lot of me lying down and my friends did eventually return with food and I ended up just watching them as they enjoyed the rest of their evening but by the next day I felt better save a massive headache and thanked god I came out of that fine and most importantly came out without my parents finding out.

Kids, research what you're taking first and never just take MORE if you aren't "feeling" it!

TL;DR Took a shit ton of Oxycontin and lost consciousness several times
