Nootropic users often take them because they want to stave off drowsiness and remain alert. That’s why they’re using the likes of Modafinil or Adderall. However, the reverse effect is that they may unwittingly trigger sleep disorders. Insomnia and unusual physical tiredness are commonly reported as long-term side effects.
Nobody wants to deal with these but they’re a genuine risk. ADHD medications are particularly risky in this regard because pharmacists create them to engage with the body’s chemical imbalances. That’s why it’s important to consult a medical expert before recklessly using them without a prescription (via Turnbridge).
