It's actually in one ear, my right one and it's high-pitch like what you hear from the tube being on with no channel, though it doesn't bother me much. The dizziness is whoozi. I can drive most of the time, but I just feel like detached from my body sometimes. Do you think it's the flu and when I take NO2 my body gets like a caffeine high and that makes me unstable? I remember caffeine doing this to me when I have a cold and I take something caffeinated. And NO2 has to be taken in the morning without any food, just water. So do you think my body takes it pretty rough when it's trying to get rid of this virus?
