If you cant think of anything to do inbetween chapters, and you love the manga as much as I do, just stop reading the chapters. I havent read the past 2 chapters and I dont plan on reading a lot of the ones to come. The reason is why wait a week for 18 pages and the last page is ALWAYS a cliffhanger? If your addicted to the manga [like me] its far more rewarding to stick it out for a few months then marathon through the chapters.
Its easier than it sounds. Fill up the time with school, a job, movies, video games (storm 3 eats up about 30 hours if you play the campaign once, then complete all the missions. I plan on replaying the game in the other voice setting too once i finished the remaining few request missions), other manga, and if you REALLY are bored re-read the ENTIRE manga up until the latest chapter. That should take you some time to do. If you speed read through chapters then re-watch the entire anime.
