I'm surprised no one has mentioned this yet but Aimo Koivunen, the Finnish soldier in the Continuation War who famously took 30 pills of meth and went on a (allegedly) two-week drug trip in the middle of Karelia's winter.
Aimo Heilmann is a former freestyle swimmer from Germany, who won the bronze medal in the 4x200m Freestyle Relay at the 1996 Summer Olympics in Atlanta, Georgia.
