Like Laura said, getting up and moving a little can definitely be helpful if you can do it. I have a hard time with it since I feel so unsteady, but I try. Mine can last for long periods of time, which is why I take Klonopin as needed, but if you can stay away from that sort of medication and resolve these on your own with other methods, it would be far better for you.

I have a couple of things that help me. Sorting and folding laundry is a very good way to get my mind on something else. Sometimes I'll turn the TV on and even just listen while I get everything done. There's something strangely zen about folding. Maybe I should try origami. :P

The second thing is video games. I love all kinds, but the exciting ones are not what works in this kind of situation. One game in particular called 4 Elements is soothing. I play it on my iPad but it may be available for phones too. I don't think it's a computer game, but I could be wrong about that. (ETA: I was wrong! The game can be played on your computer. If you Google it, you'll find it on Shockwave's website.)

I hope you feel better soon.
