Hahaha.... yeah as long as you get up every hour you should be fine.It's actually supposed to be like that for ANYTHING your doing. I guess that's why in college they're required to give you breaks, they can't hold you for hours without letting you out.Even though you could just leave anyhow, they don't care. I wouldn't suggest replacing it with smoking... xD haha jk.. no but really wouldn't :P.I used to smoke a pack a day -.- Sooooo glad I quit, so much less stress from them stupid sticks. Whoever said they release stress were right, until you can't have one the second you want it then your like OMFGGGGGG. Haha.Also remember as a teenager underage, you'd like smoke down to the butt lol just because you didn't wanna waste what you couldn't always but. Then you hit 18, after a while, your smoking half a cigarette and throwing it to the side then lighting up a new one like your rich or something :P.
