I had the EarthCalm for many years and I never got used to it.
The problem is my thyroid swells up when exposed to too much energy. I think that affects my brain indirectly because sometimes I have trouble thinking straight and I feel off balance. It probably puts pressure and my spinal cord which affects my brain and balance.
I tried amethyst for the computer and it does neutralize the stress and tension caused by the computer. However since it's emitting energy my thyroid swells up which actually is worse than the stress and tension because I can't think straight.
Maybe there is a crystal that only absorbs energy???
Or I might try orgone.
