My daughter has been in recovery for over two years now, doesn't live at home, and I still get triggered all the time. I can leave my purse laying around, credit cards, cash, etc, but phone calls from and for her still gets my adrenaline going.
I went through 3 years of absolute hell, so I imagine it may take a little while longer to stop subconsciously responding. I usually take a really deep breath in through my nose, and exhale slowly out through my mouth, until that yucky feeling passes.
I hate ptsd and feel like Pavlov's dogs, sometimes.
