I'd paid out of pocket for a 8 week acupuncture treatment last summer. In my case, I used to feel relief immediately after the treatment for a few hours - but the symptoms would return pretty much the next day. However, it helped in getting the body to stabilize in general.
There have been studies done where they've found that the transient relaxations of LES reduce while one is getting the acupuncture treatment.
