Protection Charm

First; remedy. Get a couple nights in a row of proper sleep (No being up all-hours playing video games), have a good glass of water each morning, and do something mildly physical and outdoors like a short walk. Or barring that, Do a mindful meditation to center and release tension for ten or fifteen minutes in the morning. Spend the time visualizing light and warmth flowing over and through you. Then go about your day.

Next; prevention. Ideally, when working magic and particularly when primarily working with energy it is more ideal to channel energy through yourself rather than to solely input your own. As I like to say, why be the oasis trying to water a desert, when you can be a pipe that draws the ocean?

On a side note, this is one reason why the elements/deities and the keepers of the gates are usually called on in making a sacred space and/or performing larger workings. It is about asking these sources to provide the energy you need to charge that space (-making it- sacred) and also to fuel your intended goal. The gatekeepers are there to open the path and... in a sense regulate it. On a personal scale channeling is in essence becoming your own gatekeeper internally. Becoming a path for energy to follow between source and goal. In doing so not only do you retain your own energy, but you can end up feeling refreshed and energized after a working. Sometimes even a bit 'floaty' or uplifted- which is why it is also good to follow up a working with some grounding and centering. To get your feet back on the ground where they need to be- even if your head is in the clouds.
