It just started this morning. I had a cup of coffee, a bowl of beef noodles and sausage with rice for breakfast. Then, after I few minutes I started to burp repeatedly until I felt queasy until I vomited everything I just ate. In fact, I wasn't able to finish my breakfast because I was already feeling nauseous. I'm a 23-year old obese girl.... And I highly doubt that I'm not pregnant because I just had my period a week ago. I dunno if it's because of drug overdose or what. I took 2 tablets of Biogesic (Paracetamol) at the same time last night to double the dosage. Actually, I ate lunch around 1:30pm and until now (3:39pm) I still feel queasy. Every time I burp, I think it's acidic because it's bitterly sour. I really dunno what's happening or what's the cause of this one. Please HELP!!!!
