Blackout. Welcome to the asylum. You will find some crazy $h!+ here for sure, but you will also find the most rock-solid, dedicated, awesome levels of support for you and your quit that you simply cannot find anywhere else. For now, you need to read as much as you can about how your brain has rewired itself over the course of your tobacco use. Start
here for one of the best primers I have ever read. Drink plenty of water, get plenty of exercise, and rest when/if you can (for me it was like a week before I finally slept through the night without waking up every two-three hours drenched in a cold sweat). Engage your quit group (lots of like-minded quitters in Sept '16) and exchange numbers with them. It's weird, but somehow texting/talking to someone going through exactly what you're dealing with actually works to help pull you through the low points and you will come out stronger in the end. Do whatever you need to in order to keep yourself from breaking during the craves that will surely come, even after the so-called physical withdrawal has ended. Work this program, and I guarantee you it will work to crush your addiction to that insidious weed... Quit on, brother!
