I tried nicotine patches (lifelong non-smoker). I didn't see any benefit. I was hoping I can focus more on some boring stuff I needed to get done against a deadline. I just didn't see anything. I then disclosed that I used nicotine products when I applied for some life insurance. They wanted to put me in the smoker category, I had to spend time with them to explain I never smoked in my life, and the nicotine patches were not for smoking cessation, but just to improve focus.
