Hello thanks for asking from Health Care Magic It is common to develop delayed depressive symptoms, anxiety and increased craving even after months of cessation of smoking in a chronic smoker. This is also called as protracted withdrawal. You have passed acute phase of withdrawal by use of nicotine patch but still protracted withdrawal symptoms are causing craving, want for smoker again. I would advise you to consult a Psychiatrist again for proper treatment of this anxiety. Commonly Bupropion, Buspirone are the drugs which are used in smoking cessation to reduce anxiety and craving. Varenicline is also an another option. The drug should be taken for long term basis and will result in reducing anxiety. Visit a psychiatrist for details of prescription of these drugs. Try relaxation exercises and yoga to keep yourself relaxed. Thanks, hope this helps you
