Thank you for your question
Ideally speaking, when you start an antibiotic you should complete the course as incomplete course lead to increase in antibiotic resistant bugs.
It is good that your symptoms did improve with augmentin so you should continue taking it. You can visit your doctor or the ER and ask them to prescribe more.
Or, another thing that you can do is that upon reaching Singapore you can go to the doctor there and request a prescription of augmentin.
Let me know if you have any further questions.
Do rate me for my services when you are satisfied.
