Bests & Worsts Reviews from Amazon

I have heard lots of good things about light therapy & really wanted this to work for me, but even just sitting in front of it for 10 min made me start to feel really dizzy & sick to my stomach. I followed the instructions (not looking directly at it, having it at an angle, etc) and tried multiple times over the course of a month, even trying just 5 min and trying to work my way up but it never did a thing for my energy or mood and just made me feel sick. I would like to know if there is still a way to return it and get my money back even though I'm past the return window (which was Feb 7) to do it through Amazon.
