I have been on psychostimulants for many years,i believe since I was nine or ten. I an now eighteen. I have been on such a myriad of different medications that I could barely begin to recite all of them (sarcasm, but really I have been on a shitload of different formulations/types of speed. In response to the above stated question, I have taken RIDICULOUS amounts of both adderall and vyvanse in a relatively short time period. This is going to be an extraordinary feat so read on to be amazed.
I was in seventh or eighth grade, and an avid world of warcraft (WoW) player. I'd noticed that I had trouble sleeping when I took it, (i already stayed up until 5 am to get the most play time in and be able to farm materials for gold when theres few others doing so) so I went to the medicine cabinet and got my 90 day scripts of addy and vyvanse (my doc was the shit when it came to prescribing meds) and since I'd been on them for around 5 yrs I had a tolerance, so I started out taking several of each. Enticed by how elevated my playing ability was, and my level of alertness, I continued taking several every few hours, loving the amazing rush that speed gives (i have an incredibly addicting personality, I would later end up using heroin by age 16).
It was the summer and my dad traveled 5 days a week year round, and I was a very rebellious adolescent, so my mother left me be. Two days, dozens of 30mg adderall and 50 mg vyvanse in, I.went to my friends house to have a WoW get together, and subsequently brought the pills. I noticed that after a few days, I was at a constant peak due to redosing. At about day five, I started to have lapses in time. While my friends slept (i offered them some of the miracle pills but they said no) I would play like a fanatic and eat the speed faster than my body could process it, and would unknowingly black out and come to several hours later for a brief period of time with new items and giving people advice to people on how they specced incorrectly. I'm amazed now how at age thirteen and fourteen I was able to have highly intellectual conversations with fully grown adults, this drug really is powerful, and I fully believe it to to be a super-drug.
This continued for three and a half days, and totalled eight and a half days. I do not recall a great majority of it, but I passed out after taking shots of vodka and drinking beer (one of my first drinking experiences) and laying down. I fell asleep on a monday at 8am, I remember this only because my friends parents left for work, and woke up on thursday with an annihilated immune system. Upon returning home I took even more pills and after one more night of gaming, felt horribly ill and went to sleep. When I woke I had a horrid cough and was taken to the doctor. I was diagnosed with severe pneumonia and had to be put on a bronchilator (spelling) right before my family and I went on vacation to california. In conclusion, this is an awe inspiring drug, both adderall and vyvanse, but if abused enough has severe repercussions.
I am now eighteen, as previously stated, and that was my first, yet unintended abusing of drugs. I have since became fascinated with psychoactives, and have done extensive research on all drugs (erowid is a close "friend" and I have subsequently used a great deal of hard and exotic drugs, which first began when I took MDMA at age 15. I abused MDMA like I did my meds and it has lost its magic. This continued when I smoked methamphetamine a week after I turned sixteen, and used various 2C-b,e,i phenenthylamines, and my current drug of choice is heroin.
In conclusion, when it comes to euphoria, adderall IR is in my opinion the clear champion for those with a significant tolerance to stimulant drugs. 2 30mg adderall IR get me well through a school day (5 hours) and vyvanse not giving me any euphoria, just a generic"speedy" feeling. I'm currently on 150mg vyvanse, and it is great for concentration, as I've never articulated that ordeal in such detail, or ever had the patience to do so, but I as an addict, love that rush I get from adderall IR.
I probably took in upwards of one or two thousand mgs of them, albeit there were invariably some times when I missed the usual dosing pattern during my black outs. I have had people believe I am making up this story but I see no reason for me spending the 15-20 minutes to fabricate this event and type it from my phone. My life at the moment is an (in)direct consequence of this event, and it releasing the monster of an addict from inside of me.
