what was the B12.....if you are in the USA the limits are too low....many persons are symptomatic when their docs have said there is no problem....most persons find a very steep learning curving with the gluten free diet.....so unless you are eating straight from your garden you may be getting glutened and not know it....lots of whole foods and label reading...and some persons take longer to respond....you had to "work your way up to" that high reading, it will take time to come down....keep a diary of sx.....you may have improved, and not realized it....good luck
