    Reset a few days for acute tolerance

    Tolerance Decay

    Full tolerance 2d Half tolerance 7d Baseline ~14d

    Anecdotal stimulant patterns suggest rapid tolerance accrual over 1–3 days with partial reversal over 1–2 weeks of abstinence. Avoid back‑to‑back days; schedule at least 7–14 days between sessions to reduce escalation and comedown severity.
