The nausia has had mein bed today and the burps are making me feel quite ill. I have reasearched it on the net and nobody seems to know what it is?????
I've always believed that type of bad breath (what you described) was usually a sign that one is not eating properly or may be constipated. Try eating balanced meals each day and if it continues, make an appt with your doctor to find out what (s)he thinks may be the cause and what you can do about it.
