I think you have to decide what you want down the road; good grades/schooling or the fun of the game. I had to leave Facebook because I was stuck in several games and spending more time there than on another site I found more beneficial to me. So, I quit going to Facebook and went to the other site again instead.

It doesn't sound like you want to give up the game, you're wanting your cake and to eat it too Don't know that that can work because you're letting yourself get away with playing the game because you want to. There's no "easy" way; it's all about what you really want; decide that and then go toward what you want rather than avoiding the effort, pain, discomfort, or whatever.
