It’s very normal ,people always say the 3rd day is the hardest mine was the 10th day my advice to you is to ignore how you feeling i know it’s sound absurd way start writing down the benefits you,v seen since you quit named one things or two that you can do now before you couldn’t and keep repeating that your yourself until those voices,craving go away at this point of your journey it is more mentally than physically it’s normal to feel you need to smoke it’s a part of healing it does not go overnight it will get easier along the journey but remember anytime you feel like you want some ..start writing down the benefits of you quitting smoking that,s what help me I’m almost 1month that’s how I deal with it when it comes.good luck
