Since you smoke 3 to 4 cigarettes a day, you are a light smoker, which is great because quitting might be easier. For your level of smoking, short-acting Nicotine Replacement Therapy (NRT) like nicotine gum, lozenges, or mouth sprays are excellent to manage sudden cravings on demand. Low-dose nicotine patches (7mg) can also provide steady daily support. Prescription medications like Varenicline or Bupropion are highly effective but are typically reserved for heavier smokers. Combining NRT with behavioral support (like counseling or quitting apps) doubles your chances of success. Please consult your doctor or pharmacist to customize the best plan for you.
