Are some people allergic to negative ions? I bought a pink salt candle recently and took it back to the store. I felt horrible for the three days it was plugged in and lit. In the last hour my husband opened up all of the bedroom windows and turned on the ceiling fans. A thunder storm is threatening and I can smell the nitrogen in the air. All of a sudden I am getting that same tired, sick feeling. Normally I am well, happy, and energetic. Not right now. I feel as if I could throw-up.
