@weab00 doing God's work.
Also worth noting that that 200mg was the low-dose version of the SPI clinical trials. Their results, for Meniere's at least, were better when taken at 400mg, if I remember correctly - 95% improvement relative to placebo (200mg saw 65% improvement). Value for money though perhaps doesn't work out to take higher dose - twice the money and only 30% more benefit. I have no science to back this but perhaps some middle ground of 300mg a day could be a happy middle ground.

@__nico__ if you do go for this, make sure to look into how you're supposed to take it because I don't think any of these labs deliver it in a form that's ready to take orally.
Edit: and those results were I believe for a 21 or 28 day course. A week might not do anything.
