I am 22 years old, I have been smoking cigarettes for the past 3 years and now I hav decided to quit smoking. I used to smoke at the most 2 cigarettes per day, but last week I went on trip with my friends and smoked about 30-40 cigarettes in 3 days. After the trip I felt so bad about myself that I decided to quit smoking once and for all, now I have smoked any cigarette in 4 days. But I came to know from internet that quiting suddenly will cause serious issues on neurotransmitters and on health. Please guide me with the situation and tell me if I need to take any special food to increase neurotransmitters.
