I’m quitting for a colonoscopy. HELP!

So clearly I’m not in the position where I want to quit so this is really difficult. This is my first day without smoking and I’m already suffering. I’ve only been awake 2 hours and all I want to do is smoke and feel normal. What are some coping techniques I can use? I can’t exercise because I have exercise intolerance so that’s not an option at the moment. Also I’d like to mention distractions aren’t really the best for me because it usually either doesn’t work or has the opposite effect. I know there has to be some other kind of coping technique.
