I can't tell you for sure that you wont continue to be sensitive. You may decrease being triggered if you do as you suggested and go more for less time so you can see if more exposure helps. Perhaps even go and watch others shoot at targets? Perhaps wear something over your ears to reduce the sounds of the guns going off? You may have done that already, idk.

I wonder if you could even go and tape the sounds and bring the tape to therapy and play the tape while doing emdr.

Personally, I don't think a person can expect to completely erase the ptsd sensitivities. I think a person can reduce the intensity.

I am sorry because I know first hand what you are describing experiencing. I don't have combat/service related ptsd, but I definitely have ptsd so the symptoms are the same. I share the same desire to want to be the me before I developed the challenge of ptsd.
