You just need to stop for a while. Your tolerance has gotten really high but if you stop for like a month it will totally drop because all the THC will be out of your system. Even a much shorter wait will give you great results. Exercise is good to because THC is stored in the fat cells so some good cardio and shit will get the fat flowin and the THC will enter your bloodstream again and you get high that way. Mainly though, you just need a break and it will be all good.
