Patient :All of a sudden, I am no longer able to tolerate any caffeine. I am getting funny feelings in my head and having anxiety attacks which cause dizziness even after one cup of coffee. I had been drinking 3-5 cups per day without any problems. This started one morning about a week ago. Is it possible to all of a sudden no longer be able to have caffeine or is there another problem ?
