Your call. Many in recovery reset to Day 1 after a relapse; others count continuous days and note the lapse separately. NIDA treats SUD as a chronic disease — relapse rate 40–60%, comparable to hypertension or asthma — and does not treat a lapse as treatment failure. What matters clinically is re-engaging fast. If relapse is recent, call
(833) 567-5838 — a specialist can help adjust treatment level (step up from outpatient to IOP, or residential).
