Strong euphoria and anxiety/jitters with moderate focus and stimulation
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
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.
