My long term abuse and addiction to Ritalin and amphetamines in my teen years has damaged me with permanent damage, I can no longer handle much any stimulant without experiencing dysphoria , feeling like I'm crashing through the whole duration and not feeling any of the positive effects, hell it naturally affected my anxiety and moods to the point where I literally feel like I'm crashing on amphetamines when in reality its how my natural anxiety feels now. Fast forward 15yrs later where I abstained, but recently picked up. When I take adderall, I'm only high for an hour then I start to crash, and the high lacks all the magic adderall provided once upon a time. Now, I zombie out, obsessively jerking off to youporn on Chromecast for 15hrs at a time, feeling like such a creep afterwards, how sick my mind gets sexually on stimz.
So yes, adderall use has damaged me and sensitivity thru the roof
