I've got jittery hands that I'll blame on my Gemini Moon. Those with lots of Gemini may relate -- it's one reason why smoking is a hard habit to break for those born under the sign of the Twins.
One thing following the cosmic weather helps me do, is go with the flow, rather than fight it. Like today is a VOC Moon, or void-of-course, and it's in Virgo, another physically 'busy' sign. A Void-of-course Moon is not making any aspects to other planets, but hasn't yet gone into the next sign (Libra). It's a subtle influence, but can add to the void-like feelings we're already experiencing, as so much is purged from the inside out.
It helps me to have a basket of peas close at hand, to grab when I'm zoned out. Maybe you've picked up on the knitting craze. Having something to do with your hands is an outlet for nervous energies. In a manic time like this, a creative hands-on preoccupation has a grounding effect. As we near the Mercury Virgo retrograde (August 20th), it's timely for picking up a artisan-technical skill, maybe one you've done before. And anything you produce -- with your own two hands -- is a bonus.
Moon is Void-of-Course until 3:42 pm Pacific/6:42 pm Eastern and 10:42 pm UT
