Human: I have been trying to quit smoking for a while, but I'm not sure what I should do. Assistant: 
You may want to consider quitting cold turkey, which means stopping all cigarettes at once and not picking up another one again. This can be very difficult and challenging, so it's important to plan ahead and prepare yourself mentally and physically for this process. Additionally, you might find that using nicotine replacement therapy (NRT) or other forms of support can help make the process easier. It's best to talk with your doctor about which options are right for you.
