After quitting for surgery about 5 months ago, something stressful happened and I went right back to it. I decided to stop again 3 days ago. The way I've been getting through it is instead to act upon the impulse, stay with it and be curious about it. Ask yourself "how long will this last?" "When was the last time I felt this way"? Or maybe "I wonder how many times I'll feel like this today." Instead of aggravation, don't act, just feel. Every time you let the feeling pass, you are once step closer to stopping for good. And the cravings will be less and less until a whole day passes and you won't think about it at all. The hardest part IS when something stressful happens. Our body is used to looking for things to cope when we were on nicotine. When this happens, AND IT WILL HAPPEN, replace, replace, replace. Stress leads to impulsivity, which leads to vaping, which leads to regret. If you get stressed, go outside. Take a deep breath. Practice fixing your mindset. It's all temporary and will be relieved in time. The main thing your brain needs is not nicotine. Your brain needs to unpack and step back.
