Attention is influenced by sleep, environment, stress, interest and health; difficulty focusing is not automatically ADHD.

Notifications and task switching impose a real cognitive cost. Structured work periods and environmental changes can improve focus without a supplement.

Start with the obvious constraints

Sleep opportunity and timing.
Single-tasking and fewer interruptions.
Clear next actions and realistic work blocks.
Assessment when difficulties are lifelong or significantly impairing.

Stimulants and nootropics carry risks and should not be used to self-diagnose.
