Replying to Smoking too much/often

I feel like I personally have been smoking too much pot and too often. For me personally, I maybe smoked earlier at a rate of maybe 1 blunt every 2 weeks. Now I've been smoking 3 times per week with my friends when I'm free and before my PM class to be sure I come down before I even drive. I still get my work done and all that, but I've just been smoking much more. Should I cut back and go back to my previous amount or just stick with it?
