Let the chapters build up, and just take it slow trying to catch up to the current chapter. I use to do it before I got deep into the manga, but now I gotta have my weekly dose.
I always read the 3 previous chapters when the new one comes out just to remember what I'm getting into, and one episode before the new one unless it was a filler.
At one point the anime got so boring and bland i stopped watching naruto for like 3 years. then i got into it again, then i got bored of it. now im into the manga and i just can't stop reading it. Its like a drug LOL
