Watch out for Stevia
Seen a lot of comments on here about being dizzy, and having headaches, brain fog, and so forth. Just wanted to let it be know that I was having a lot of the same symptoms: dizzy, headaches, congested, yellow snot. Had them off and on for about 4 months, and went to 5 different doctors to try and figure out what it was. I was put on antibiotics, then told nothing was wrong with me, then told that I had a deviated septum and was put on Nasonex. None of that helped. Anyway, long story short, I finally figured out that it was the Sobe Lifewater that I was drinking, and I'm guessing it was the Stevia or something else that they put in there. So be careful, and look out as to what goes into your system.
Also, that nasal spray they put me on seemed to have a similar effect of making me feel all spaced out.
Most of the doctors that I saw were really not that great at diagnoses, and rarely spent the time to ask me more then 3 questions about my life style, diet, and so on. So I had to figure this out on my own, which was hell, which is the reason why I'm posting this now. I hope it helps someone out there.
