My sleep continued to be worse on the third night after my one time use of the Vie Light. I had a wired toxic feeling all day yesterday, which did not go away by the evening, in spite of all my attempts to quell it with various remedies and some acupuncture. This wired feeling was similar to what I get when I've taken too high a dose of methylation supplements, which I haven't taken at all these past several days to make sure THAT wouldn't complicate matters. It made me wonder, though, if the Vie Light's stimulation of my brain could have revved up methylation (via the HPA axis) and pulled out some heavy metal toxins. That could be what caused me to become so wired these past three days. It's my best guess as to what's happening. I called the company rep yesterday to ask specifically about how common overstimulation symptoms are. The guy I spoke with told me that "the Vie Light does NOT cause overstimulation." He said, "It had to be something else that did that." (He obviously has not dealt much with hypersensitive people, where ANY symptom is possible at ANY time.) I told him that I had not done anything differently in the past few days, and that the symptom of being very wired and overstimulated began within an hour after my 15 minute use of the Vie Light on Thursday. I also told him I suspected that the Vie Light could have caused some detoxification symptoms, by increasing methylation. He said "NO, it couldn't do that," insisting again that the Vie Light could not cause overstimulation or detoxification. Then he went into the same speech he gave me Thursday, about how the Vie Light works to balance circadian rhythms in the brain via the pineal gland, and how it regulates the sleep/wake cycle, and how it increases mitochondrial functioning... etc. He didn't let me get another word in edgewise, and ended by suggesting that I try the Vie Light at least 4 or 5 more times to see if I get the same reaction. (I don't THINK SO! is what I wanted to say at this point, but instead I simply said thank you and goodbye.) This guy apparently did not get it how VERY uncomfortable this reaction has been, and unfortunately wasn't in the least bit interested in hearing about it. Like most company reps, he was primarily interested in telling me all the good things about his product and how well it works, and how minimal side effects there are. Very typical and predictable, but not very scientific, considering that the Vie Light is a product that aligns itself with "40 years of scientific studies on low light therapy." I will continue to mop up the toxic overstimulation left behind by the Vie Light, and see how long it takes to get beyond this mess. I will keep you all posted.
