Erase porn escalation's memories

What do you guys think about the use of propranolol to "erase" traumatic flash-backs and bad memories, I'm contemplating using it for the flash-backs I'm getting from my last porn escalation, and since I didn't dive deep into it there isn't much memories to erase.

What I understood from the studies is that propranolol is taken 1 hour before exposing the patient to his fears, phobias and distressing memories. The drug doen't suppress the memory but blocks the emotional charge that comes with it and makes it a dull memory, with enough sessions (usually 3) the memory becomes neutral and doesn't cause anxiety to the patient. And knowing how the brain works, if a memory is neutral it will end up forgotten with time.

Did anyone try this before?

By the way, it's also used for addiction, it has some good results with smoking and cocaine addictions.
