BG - I forgot to mention to you re if it makes a difference...
I'm not sure about what your chiro said in regards to the 12 week plan, but I do know that you can feel the difference with the acupuncture instantaneously...
My NP starts with the needles at my feet and works her way up - by the time she is at my head, I can already feel it running through my body.
Over Christmas we were away, and had a few weeks where I couldn't have any acupuncture done, and I also left my herbs behind.
Within about 4 days, I wasn't feeling myself, and after 2 weeks, I just felt like crap... and was retaining that much fluid it wasn't funny...
I had a session as soon as we got home, and felt better straight away... after a day of being back on the herbs, I was back to normal.

I suffer really badly from fluid retention, so I noticed it big time... especially over Christmas, too I guess, because it was so hot as well!!!

HTH

Love Holly
