Hi Zeraph
Grancey's response is close to my own sentiments, and phrases like 'gastric reflux' come to my mind.
However ... second time in a month and this time gone on for two days means, in my English National Health Service-based language "Go See A Doctor." I'm appreciative that in some countries, people actually have to pay - but in that case, I reckon the fact tht its the second time, and this time has lasted quite a while, more than justifies a visit to get a professional opinion.
Best wishes
