I find it pretty weird that it works. I don't use it a lot, but once in a while it is handy to have. I tend to procrastinate about certain things, like calling clients with less than great news, it really helps lower the anxiety level for me. I would think it would work well for short duration high intensity cravings like cigs. I don't tell a lot of people about it, because I sound like such a loon promoting it. But what the heck, no sense being embarrassed in this crowd, we all have a few skeletons.
