If you are going to pour on a regular basis, you need to take the proper precautions. If not, you will most likely pay for it later on with health issues. You should not be breathing those fumes at all. Don't blow off the symptons you are getting, if any, to something else. If you didn't have these issues before you started pouring.........where do you think they came from? As far as headaches go, drinking lots of water does help alleviate that.
