I finished treatment a month before you did. Mine was pretty sticky but lately its improving. The other night I made brownies and had to substitute almond extract for vanilla extract and it got my salivary gladn pumping-- or maybe I just turned the corner. Mine is improving each month slightly along with the sensitivity in my mouth. Spice/ acidity was so so painful but now its getting lots better. Stil can't have thai food much un;ess its not too spicy pad thai but its getting there.
I understand your frustration. I have a whole ritual at night with the teeth to preotect them-- Its a hassle but just a part of life for me now.
