Today all I did was eating some chips then while I was getting a glass of coke I had "brain fog" I felt like I had to get fresh air, but after I realized a while glass of drink had been spilt, I have no memory what so ever of how it spilt and afterwards I could not think what so ever and I had a headache at the top of the left side of my head which was more noticable if I moved my head quickly. I do not know why this happens but I aure wish I did...
