The way I cope with this is to chew nicotine gum or take a supplement or CBD or something. I often want to just "take something".

It's not the best thing for me to do but it's like an addiction hack. Mind you I took meth, coke, heroin, etc.. all of those things..

Even better would be distracting yourself with anything until the cravings go away. Intense cravings don't last very long. Most of the time when I give in and buy some drug online, I cancel the order within a day.
