Yesterday morning, i quit smoking cold turkey. what should i expect to experience over the next week(s)?

Highly variable: depending on how much you smoked, what kind of cigarettes, how deeply you inhaled, how long you have smoked. Usually, irritability, lack of concentration, craving ("nicotine fits") and sleep disturbance. I strongly recommend using nicotine replacement (patches, lozenges, gum) rather than cold turkey, which has the lowest quit rate of all methods. Join a cessation program at least. Good luck!!!

Withdrawal symptoms: First of all congratulations! There are no side effects when you quit smoking cold turkey, but you can expect significant withdrawal symptoms from nicotine. Here are some symptoms to expect insomnia, restlessness, muscle cramps and poor concentration. I know, you can do it. Good luck!
