Nicotine withdrawal symptoms typically begin within 4 to 24 hours after the last nicotine intake, especially for long-term users. These symptoms peak in intensity around the second or third day after quitting

. The worst physical symptoms usually occur during the first week, particularly in the first 3 to 5 days. After this period, symptoms gradually lessen over the next few weeks

. On average, withdrawal symptoms last about 3 to 4 weeks, but some people may experience symptoms, especially cravings and mental/emotional effects like anxiety and irritability, for several months after quitting

. Here is a general timeline of nicotine withdrawal:

• Within hours (3-4 hours): Nicotine levels drop, cravings begin

• Day 1: Restlessness, irritability, increased appetite start

• Days 2-3: Headaches, peak cravings, anxiety rise

• Week 1: Worst withdrawal symptoms, including mood swings and sleep difficulties

• Weeks 2-4: Physical symptoms fade, energy improves, but mental cravings and mood fluctuations may persist

• After 4 weeks: Physical withdrawal mostly subsides; mental urges and emotional symptoms may continue but gradually decrease

Managing withdrawal with support, distraction, hydration, and sometimes medical help can improve success in quitting. Avoiding triggers and having a strong mental plan are important to overcome cravings and prevent relapse

. In summary, nicotine withdrawal lasts most intensely for about 1 week, with symptoms generally fading over 3 to 4 weeks, but some mental and emotional effects can persist for months
