Answer

Symptoms of withdrawal include difficulty concentrating, nervousness, headaches, weight gain due to increased appetite, decreased heart rate, insomnia, irritability, and depression. These symptoms peak in the first few days but eventually disappear within a month.

Symptoms of nicotine toxicity, otherwise known as acute nicotine poisoning, include nausea, vomiting, salivation, pallor, abdominal pain, diarrhea, and cold sweat.

A previous history of depression, use of antidepressants in the past, and onset of depression during previous attempts to quit smoking should be obtained.
