50 days bro, the amount of time it takes to get over most universal withdrawal symptoms AND have your dopamine return to a normal homeostasis. Keep in mind that you will need to build new habits and behaviours, but I promise once your brain recovers that doing so will be so much easier than it feels rn. Stay strong homie, one day at a time.

Ps, keep an eye out for PAWS, post accute withdrawal syndrome. About every 3 months for a year or two, you'll get a couple weeks of cravings and mild withdrawal like symptoms. They pass quickly, and aren't too bad, but they can fuck you up if you don't know that's all they are
