Before You Quit: Preparation Day

The day before your quit date is crucial for setting yourself up for success:

Final Preparations

• Remove all smoking materials: Cigarettes, lighters, ashtrays, and any smoking paraphernalia

Day 3: The Peak of Withdrawal

Day 3 is often cited as the most challenging day of quitting smoking. Here's why and how to get through it:

What's happening in your body:

• Bronchial tubes relax and open up
• Breathing becomes easier
• Lung capacity increases up to 30%
• Energy levels may fluctuate

Nicotine withdrawal day 3 symptoms:

• Physical symptoms: Headaches, fatigue, dizziness, nausea
• Emotional symptoms: Peak irritability, mood swings, anxiety, depression
• Cognitive symptoms: Difficulty concentrating, mental fog, memory issues
• Behavioral symptoms: Strongest cravings, restlessness, sleep disturbances

Why day 3 is so hard:

• Nicotine receptors are at their most sensitive
• Your brain is still adjusting to life without nicotine
• Psychological habits are still very strong
• Sleep deprivation may be affecting your mood

Remember: If you can make it through day 3, you've overcome the worst of the physical withdrawal. You're literally on the other side of the mountain. For more on what's happening in your body, see our health benefits timeline.
