I ditched the nicotine and thc, alcohol mostly gone but caffeine still got its claws in me.
I made myself a promise when I finish my current project (it's a bounty, and will be plenty of money to let me do nothing for a week) I'm gonna just have hot baths, sauna and get massages and sleep.
Eventually I have to stop because my blood is too thick and acid and caffeine is the number one cause.
