Military pilots are only provided performance boosters in special circumstances, not as a general daily event. Such circumstances include long ocean crossings when flying as the only pilot, or in extended combat tempo operations where constant sixteen+ hour days can wear you down. Even when provided such medications it is under the direct care of a flight surgeon who is usually embedded in the flying unit and knows in depth the medical history of each of those pilots. Additionally, pilots are tested in advance of their reactions to such medications so there's less of a surprise when the need for them arises. They're also only issued by the relevant medical authority and voluntarily taken or not taken as the situation dictates.
