herxing? magnesium IV treatment?

So since my body responded so well to the Flagyl after last week's scary diarrhea episode, my LLMD thinks it must have been C. diff... and now I'll be taking it for 10 more days, and then we'll pulse it a little while longer to kill any remaining spores. In the meantime, she also thinks I am herxing... my muscle cramping has definitely gotten a little more intense, and my neck has been sore. Today, I went in for a magnesium IV treatment.... beforehand, I was feeling a lot better, and we assumed that it would help me even more... but it completely knocked me out! My head has been wonky for the rest of the day, very fuzzy, I can't think straight, and I'm not so sure I should have been driving.... and my energy has been completely zapped. I'm at zero. Zip.

So what I'm wondering is, can a magnesium IV treatment intensify a herx? Would a detox bath right now be overkill? Or do you think it would help?

I wasn't suggesting that the magnesium would kill the lyme... I'm wondering if would, however, make the Flagyl more effective than it was at killing the lyme... hmmmmm.... but I didn't know that too much magnesium could do this..... interesting!
