I had five concussions playing soccer between July 2012 and March 2013. I'm still looking for a solution to speed up my recovery and I came across Gyrostim.

I read many discussion threads talking about how this is pseudoscience. I understand that there has been no double-blind controlled study. However I find it strange that I haven't heard of any people for whom Gyrostim has not worked. I feel like if I paid a bunch of money and it didn't work I would go on Facebook or Twitter and talk about how it was a scam.

Does anyone have any actual experience with Gyrostim?
Both positive and negative experiences are appreciated!

Thanks,
Andrew
