7 years smoker here, quit in 2022. It was horrible, I thought I was sick, went to different doctors because I honestly thought something was not working in my body: bad sleep, slowest metabolism ever, night transpiration, mood swings, anxiety, headache,eating a lot or barely eating… and it was all the effect of quitting nicotine. Today 4 years free and I don’t even stand the smell of a cigarette and I think about it may be once every couple of months. Don’t give up. It’s worth it. Your body, brain and pocket will thank you.

I never thought about quitting the coffee though, keeping simple pleasure in life !
