Indeed you should not do just the liverflush but also improve you lifestyle, food etc. In the beginning that person might have had the migraines because of the toxins reaction. I got severe sinus pain,it went away after a couple of weeks, but kept going. After a year I was off 3 anti-depressants (used some 15 and 40 years), no more allergies and aches and pains through the body and no more gallbladder problems.
Don't forget an accupuncturist makes money from you going there. As long you have insurance you might not mind this, but I had to pay for the visits myself when I went for backtrouble. She always told me my liver was weak, but I improved my lifestyle but I don't know what she would say now.
But everybody should do what they are comfortable with.
