I like petting soft things. This is especially helpful for calming frantic or scattered energy, though I'll have to pay attention and see if it actually helps regenerate energy; I haven't noticed this before.

I find some sounds help me too, although it seems to change based on mood and other unidentified factors (could be the phases of the moon for all I know), and I can't always pin down what sounds will help when.

Oooo! Food! I actually eat a fair amount of fruits and vegetables during my work day, though less so after I get home. I'll have to keep yogurt in mind, since I don't usually have it in the house but I do like it. I'm also looking for something to take the place of energy balls on occasion, for variety, and yogurt with mix-ins might be a good choice.
