Smoking once a day.

Bit of a weird one here, but I keep having cravings for cigarettes. I have never smoked, I'm not around smokers daily or that often. My partner does smoke but we're long distance so I'm not with him much, yet I keep craving it! I've also had several dreams where I've been smoking and it's such an amazing calm dream that I wake up thinking 'man I need a smoke!' even though I don't know what it's like 😂 I'm thinking of smoking, but just one in the morning when I wake up and no more. Is that possible to do? I don't really want to be a heavy smoker and I don't want to smell like cigarettes so I'd smoke before I shower each morning. Is it doable or will I just get addicted and start smoking constantly?!
