So, this ringing/hissing/buzzing has been going on for quite some time now. I noticed the weather (rain or snow) causes a spike. I've also been trying to identify dietary triggers and I definitely have noticed that MSG causes an instant spike. I also notice that I have to watch my salt intake. Caffeine and soda don't seem to do anything as I have previously eliminated them with no benefits. However, one that I have been noticing but ruling out for quite some time is...TAP WATER. Could this be? Or am I insane or something? The last few days I have noticed that I wake up relatively quiet. Then I eat breakfast (eggs), then I drink my diet mountain dew (i relapsed back to soda oh well), then I drink about 2 bottles of bottled water. It still is quiet. Then I start filling my bottles up at the water fountain and drinking those the rest of the day. I'm on diuretics so I drink/pee a lot. Anyway, midway through the first bottle of tap water I notice my buzzing increases. Then it increases further the rest of the day. When I get home later and eat dinner it usually subsides a bit. I don't drink tap water at home just bottled water or juice or something. Even when I have my beer or wine or whatever at night I usually don't spike. The thing that is making me really identify tap water is that when I work my second job I drink tap water there too. Those nights I ALWAYS spike while I'm there. Then, all weekend when I am home and drinking soda, eating etc. but no Tap water I am usually quieter. So, could this be the culprit? What could possibly be in it that I am reacting to? And does anyone else notice this? What other triggers do you notice?
