I always follow your progress wannabecee as we are the same age and started round about the same time. I haven't seen any increase for a while but, like you, I feel I'm about to have a growth spurt, lots of aching and tingles. Been toying with the thought of getting the XLs even though I don't fill the large domes yet. Wondered whether the XLs might help to fill out the tops a bit more.
