In trying to think of ways to otherwise preoccupy myself other than eating, I think painting might be a good one. Obviously it's not very practical for when at work, but I think it's something I would like to do none the less. I've also picked out a few coloring books for adults and colored pencils that I think I'll take quick little breaks with here and there when I feel the urge to eat. Art has always relaxed me, even though I'm not good at it. Pretty much any activity that requires the use of my hands in a craft-type fashion.
I built the rabbit hutch, I've put puzzles together, sewed a plush companion cube and pair of fuzzy dice companion cubes, in college I built beer pong tables. I like to create things with my hands, which is why for a while there, I dabbled in welding as a potential profession. The fumes and hot slag in your eyes though really cuts down on the enjoyment of joining metals together. Crafty creations I think is the general area in which I will choose to apply my free time. I think that's why I enjoy tending to my succulents as well. I cut, propagate, arrange, and fiddle with all of my little succulent plants. I started out with 6 total, just in the small pots, and have multiplied that several times over now. Hell, I turned one aloe plant into at least 20, sure they're not huge yet, but they are distinct separate plants (and great for sunburn too).
