Hi - I feel the same that my brain is loose in my head. I have often joked about needing a stabilizer like a ship. I have been into fast long walks lately and 2x in this last month I have ended up with major headaches and vomitting and then the inevitable jabs in the you know where. I now know for certain that I have to be very very careful about the level of physical exercise I do.

Since purchasing my "black box" which reduces back ground noise I have found the car a lot better as a passenger but sudden bounces or jerky corners give me a headache.
