I know how you feel! i was addicted for the longest time and then I finally forced myself to stop doing it because I needed to pass a test for my job training that required severe concentration. Don't worry! You can stop but it'll have to be slowly! Don't buy any for a week or start pacing yourself with less and less. Give yourself a goal, like you'll only take it in the evenings or on the weekends. Then when you can, stop for a couple days at a time. Whenever I break down and robo trip again, it takes me almost three days to stop taking it. I usually promise myself that I won't buy it until three days later. Then I don't want more by then. Try it! If you're feeling sick it's cuz your body needs at the very least a break!
