i'm glad it's been helpful for you.
depending on the offense, losing computer time if you stay up late can be extremely effective. so can losing privileges like playing computer games. if the problem is being mouthy, there's always soap (blech.) writing essays can be a variation on lines. standing in particularly uncomfortable positions can intensify the misery of corner time (hands on my head is waaaaay worse than simply standing in the corner).
or you could just be absolutely angelic, which solves the problem without external discomfort.
