I consume cannabis the way i consume most things - binge then purge. I do this for several reasons. I like to reset my tolerance for one, but the big thing I notice is when I am getting off or back on I have huge upswings in my creativity and motivation. When I stop smoking after being saturated from a long binge, I have no desire for food and will often fast for a day or two with huge amounts of energy and focus. When I get back on I usually have some big insights and waves of creativity and motivation as well. So don't worry, I find stopping and then starting again when you feel like it, is the way to go.
