Is it possible to lose the euphoria associated with amphetamine from abuse? I abused amphetamines quite badly when I was going though a period of heavy partying. I have since stopped the drinking altogether which has been life changing. Was at least 3 months with no drug use that I tried adderall again to prepare for an exam. I then tried going recreational doses at around 50mg and really dont find the euphoria much anymore. I get nice stimulation that feels great on the come up be fades quickly. I have been realizing this happening even when I was still partying. When I was heavily using I would use upwards of 90mg in a day. I remember reading that amphetamine tolerance never really fades. Any input?
