Relax. It's normal. Eat something nice. Don't just sit there doing what you used to do when you smoked. You are now different, so do something different. Bundle up, and take a short walk. Breathing fresh air is now amazing, and the exercise will help a lot.
Remember, the first 48 hours are done. Just don't try to vape away everything. Take it easy, and do other things. Hey, take a nice hot bubble bath. Make a pot of onion soup. Bake up some yummy cookies. If you are a coffee drinker, make a cup of tea. Call an old (non-smoking) friend, and visit them. Put on Steely Dan's Aija.
And take it easy with the vape. Hit it a few times, smile, put it down, and continue with all the other cool things. Don't let the vape be 100% of your day.
And OK, then, when's the last time you listened to Carole King's Tapestry?
