I do not understand this drug anymore at all and don't know what to do. I will not stop using it until I finally get the "normal" high again. I first used 14 months ago and got incredible buzz energy and fapped for 4h straight in pure euphoria just like people would often describe it. I started using again recreationaly 2 months ago and it's not like that at all anymore but it's from the same source. Just to be clear I do not expect that euphoria again but ffs at least anything, when I use in moderate doses besides not being able to sleep I feel absolutely nothing, when I go to fap I cum like usual(sober), music sounds the same, I can eat just fine etc... But if I use more I just get anxiety and can't wait for it to be over. Wtf is going on and has anyone else experienced this? Am I using too much and overwhelming my brain so I can't feel pleasure or am I using too little and then letting anxiety take control of the high? Am I alergic if that even exists? Did my brain just suddenly decide to neglect amphetamine effects for whatever reason? Any tips and advice would mean a lot to me. Snorting 2 fat lines that make my friends tweak hard af while I can eat a whole lunch afterwards(14 months ago when using I would sooner give my ass then eat anything high on speed) is just mind boggling since it can't be tolerance...
