Dyspepsia and Indigestion. Tablets )

I ate outside food 10 days ago. Since 10 days i am feeling full after a small meal too. It takes around 8 to hours to digest a small meal. I eat only morning and night very small meal because i am feeling full very soon. No stomach pain, no vomiting, no diarrhoea and no other symptoms. Ultrasound report is normal. I was prescribed Nexpro tablet and i took for 5 days and no relief. So the doctor gave me lesuride. But i understand lesuride has a lot of side effects. Can you please let me know any other tablet to help me heal soon (I do not want to go for any complicated scans or Endoscopy because this is first time i got this dyspepsia and its due to eating outside food continously. Please suggest tablets )
