Another reason why you'll fail with that method. IF your pee is tested for specific gravity, which may be likely that it isn't, you will almost certainly fail. You must take into account your creatine, electrolytes, and etc. that differentiate your pee from some water.The pectin your taking is giving you some fiber, which is a plus, but I'd say that your best bet would be to take a multi-B vitamin complex instead of niacin, then follow N2's guide like a bible and throw in some metamucil every day if you must. It really doesn't hurt to take an extra shit every day so long as your not overdoing your fiber, better to keep that regular than to throw it in at the last second before your test every week. Be as thorough as you can, trouble with the law is sooooo not fun. If you Must smoke you better have your system down like a scientist, because its really not worth the repercussions to only smoke a little. If your gunna fail a test, it would suck to do it with 1 over your 50 limit, because you need one toke a day. Might as well fail it with 500 and have a story.
