It's definitely not easy, particularly at the start, but the rewards are great. I'm still learning new things all the time. Granted, the new things I'm learning generally require additional discipline, but I'm now at the point where I can say that my fuzzy head today was probably due to the half packet of scotch fingers I demolished on the weekend. Bad things are much easier to handle if there's a reason for them. I do my best to not beat myself up when I slip or drift - my body does it quite nicely all by itself.

Good luck!
