Cold turkey is easy if you give yourself reasons to quit.
I quit a little over a month ago, and it's the best I've ever felt. I still get down, but it's a lot easier to bounce back. Anyway, here's some reminders that helped:
1. I'm in college, I don't have time for that shit.
2. I'm a more sociable and generally happier person.
3. Weed achieves bliss, not happiness.
4. I have more energy and focus to devote to my passions
5. Weed achieves bliss, not happiness.
