Hey guys -- it's very interesting that so many people are mentioning this "moving floor" phenomenon. I was experiencing something very similar - it felt sort of like I was walking on a floating dock. Id go to reach down for something in a cupboard and feel like the floor moved underneath me. At the time I was taking some SNRIs for anxiety (effexor). I decided that perhaps the medication was the culprit, and I cut my dose in half. Turns out that was a good move -- I haven't had that feeling since. It was almost instantaneous relief.Given how many of us are anxious just wondering if any of you guys are also on SNRI or SSRI therapy (paxil, zoloft, prozac, effexor, cipralex, etc)....could be contributing to the weird floor moving feeling....but maybe it was all in my head and its just a placebo effect, who knows....
