I myself didn't experience any burning sensation when urinating or nausea or dizziness. However, I did feel nauseous up to like an hour after drinking it each time. And yes, it does make you feel like you might vomit. That's somewhat normal. Just horrible tasting stuff. Makes me shudder when I drink it. But it did work for me.
As for the symptoms above that some of you are experiencing, I guess that's your call. if they aren't that bad I guess press on and finish the herbs, but if you're overly concerned I guess discontinue use and let your body regulate itself.
I promise I'm not trying to hurt anyone. Just the opposite. But like I said before your results may vary on this stuff and it is always best to see a chinese doc or herbalist yourself to get a formula tailored to you.
Good luck!
