Wow Julie. That would be very annoying! This is just off the top of my head, but I'm wondering if a therapist could help to "train" the brain. In therapy, we are taught all kinds of things, so I'm just wondering if that would help too!
Why not call a good Psychiatrist's office and see what they think? It's worth a call, right? I would think they could give you an answer.
I wish you the very best Julie. Let us know what happens. God bless and please take care. Hugs, Lee
