Hi Teebs: I used to get the lump in my throat feeling, but not the gagging feeling. There is one exercise I used to do a lot, now once in awhile. Very slowly I turn my head to the right as far as it can go, feel the tension and stay for a count of approx. 10, then slowly turn my head back to centre, then continue to the left as far as you can, hold to a count of 10 again and slowly return to centre. Never use jerky movement, always slowly and smoothly. I find this helps too for neck tension. Worth a try?
