An ampakine-based stimulant, the new Aufwachen is a relatively new drug created in AF 260 (YE 32) to replace the older Amphetamine-based stimulants. Unlike the older stimulant, Aufwachen has very few dangerous side effects: such as the sleeplessness and 'shakes' Amphetamine caused. Instead, Aufwachens side effects are along the lines of headache and nausea when taken in either large quantities or over long periods of time.
There is still a chance that Aufwachen can be psychologically addictive and previous experience with Amphetamine-based stimulants have led it to be heavily restricted by medical specialists.
