Anyone have horrible die-off from cleansing?

I have been treating with an ND for a couple of months now. Last week, he added in a supplement to help cleanse viruses. I have EBV and possibly CMV. It sort of seem to kick in last night. I felt awful the whole night. Headache, neck pain where the lymph nodes in the back of the neck drain, racing heart, feelings of panic, off and on mild nausea, etc. I have had similar cleansing reactions before when cleansing parasites, candida, etc. Anyone else having this? Thanks. Tweet
