Three months smoke-free is a powerful milestone. Cravings are typically softer and less frequent, your routines are steadier, and measurable health gains are within reach. This checkpoint is about two things: taking stock of your progress (with real numbers where possible) and refreshing motivation so months 4–6 feel purposeful—not automatic.
Breathing & stamina
You may notice fewer coughing fits, less morning mucus, and easier walks. If you can, schedule a quick spirometry or a simple peak-flow check with your clinician. Even a home “stair test” (floors climbed before you need to pause) is a useful personal metric.
Heart & blood pressure
Smokers often see lower blood pressure and resting heart rate by month three. Log readings from a home cuff (same time of day, seated, after 5 minutes of rest) and compare to your pre-quit average.
Carbon monoxide (CO)
If your clinic or pharmacy offers CO breath testing, take it—you’ll likely see a low, non-smoker range. Seeing the number is a huge motivator.
Taste, smell, skin
Food tastes richer, and skin often looks brighter with better circulation. These aren’t vanity wins—they reinforce the daily rewards of staying smoke-free.
Mood & sleep
With consistent bupropion and stable routines, most people report steadier mood and deeper sleep. If you still struggle, it’s the perfect time to tweak routines—not your progress.

Don’t self-taper because you “feel fine.” Nicotine pathways continue normalizing for months; medication consistency is relapse insurance. If side-effects persist, ask your Qwitly clinician about timing adjustments, not discontinuation.
