When I was going through my withdrawals I really wanted to know how long they would last as well. I started reading some of the research stuff and I believe it was in one of Dr. Fassano's papers where he stated that the antibodies created in reaction to the gluten have a half life of three months. So in three months, half of the antibodies are gone, in another three months, half of that half is gone and so on. It takes a full year to eliminate your system of the antibodies if you don't accidently gluten yourself.
I started to feel better for longer periods of time around the two month mark. Lots of energy, good cheer and hope. Some of my symptoms are ramping up at other times.
Hope that helps.
Oh yes! By the way, gluten acts like an opiate on some of the receptors in the brain so when you withdraw from it some people get depressed.
I wonder if acupuncture will help remove the half-life that you researched? I have been gluten-free for 4 months and have no libido. I have also removed diary and sugar too. My labs show normal thyriod. Do you have that article or have you been through a similiar raod with this? How long did it take you?
