Jamie, Exercise will help you immensely, it will release dopamine and help you to get through craves. It will also help to tire you out and maybe you can get some sleep and sleep through some craves. Bite into a lemon, rind and all, get some really sour candy to suck on or some really hot candy, like fireballs. No crave ever killed anyone but no one can say that about smoking. Craves only last a couple of minutes, it's just that at the beginning, they seem to come on top of each other. You WILL get through this and it WILL get easier.
I will be really interested to hear how the cream of tartar and orange juice work. It sure is worth a try. We are here for you...stay close to the site.
