I just came from a party. I am drunk. While I was on my way, I couldn't feel a bump on the road in my head. This has been my major symptom since the injury. But those bumps and potholes I used to dread always didn't bother me at all after I am drunk. I felt totally normal and insensitive to them. This makes me wonder if I have become overly conscious about them and I don't actually have a physical problem. Any thoughts ?
