winnie, anvil made me remember something. My daughter had a huge problem with impulse control before the addiction, and her teachers often thought she might be ADD. She drove us all crazy because some days and moments were better than others.
After she found a more progressive p-doc last year, he ran a bunch of diagnostic tests on her, an EEG being one of them. She was suffering post concussive syndrome and it was from a long time ago, when she was a young girl. They don't always resolve on their own.
The part of her brain that was affected is responsible for impulse control. Her doctor said she was trouble waiting to happen and addiction was almost predictable. I got her started on neurotherapy right away, sometimes screaming and fighting because she was a dry drunk at the time. I know it was controlling on my part but I'd do it again in a heartbeat.
Just thought I'd share that with you.
