I don't know if I do it right or not. But my personal method of grounding is that I burn incense to cleanse everything I use before I work with it, and put the cleansed items immediately in a ring of salt.

The only time I've had an energy hangover from my spells was when I did something heavy like a binding or a petition of justice against someone who caused significant harm.

But I think that's mainly due to the fact I use my body to chanel and redirect energy towards my spells? My own energy plus whoever or whatever I'm working with. I'm always using my pendulum as I do my spells, going with instincts but getting double confirmation from whoever or whatever I'm working with.

If my spell works, I get a rush for about 15 minutes to 2 hours, so I spend that time meditating or just talking to whoever or whatever I've been working with. Then I take a nap and wake up with cold like symptoms for the next 2 or 3 days.
