I would think its possible because the reaction is based on a neural pathway that was formed & continually reinforced....but I learned in DBT, with a LOT OF FOCUSED & MINDFUL WORK old neural pathways can be broken & new ones formed. It's the same process that stroke & traumatic brain injury victims use to relearn things that ended up broken in the event that caused their problem. Harder to catch & remove in the first place but it is still totally possible with A LOT OF HARD WORK you can do it
