Davey that sounds horrible, get the headaches checked out by a doc. I get the brain freeze like stuck thing. But I can't sort it out if it's thoughts moving so fast that I can't isolate a single thought, or is it really stuck. Maybe it's like it's trying to find pieces of info somewhere in my head and there's a big pile of stuff to go through. That happens a lot with projects. I think it might be my add, idk.
