Sheila, that looks really interesting. I will look into that in the future. Those 15 seconds of listening really triggered something. I had bad headaches and nausea for 3 days after that. It wasn't continuous just on and off. It's stopped now though. I don't think that severity wise my symptoms are that bad on the whole but I do seem very sensitive to different things and the reactions I have are short lived but quite aggressive. I am discovering what things affect me gradually and accidentally in most cases!
