I finally broke down and bought one of these, and just wore it for the first hour. I wasn't expecting to feel anything different right away based on what I read, but I definitely did.

It's really kind of funny because I almost felt confused about what I was feeling. The only thing I was sure I was feeling was the current produced by the TENS unit. Everything else was muddied, including my ever-present symptoms in my toes, feet and legs.

It just cut off after an hour, and I could immediately feel all the "normal" weirdness again.

As the night goes on my symptoms should worsen, and it will be put to a bigger test. But as of right now, I'm encouraged.
