<s>[INST] I been experience bad breath for the past 6 months. I have gone to a dentist who put me on breath rx products, doesn't work. I brush and floss twice a day.  I have also experience violent vomiting spells at least twice a month for the last six months also. I burp and I always feel like my food is coming up all the time. please help. [/INST] hello thanks for the consult at hcm,, u might be having bad breath due to systemic causes, since the usual mouth rinse and other stuffs hasnt helped u,,either ways do salt water gargle thrice daily, with h/o of severe vomiting and burping u might be having increased gastric reflux ,kindly consult a gastroenterlogist for a check up and investigation, and then ur periodontist,, hope it helps,, tc </s>
