Most Bitter Medicine I ever Ate

On 20/11 I went to check up at Sunway Hospital. The doc prescribed two more additional pills for me. It smaller then the previous pills. Don't think the small pills wouldn't be bitter, it more bitter then the big one's. Why the doc prescribed two more additional pills? This is because after I ate the medication, I'll have fever so the medication is for me to control the fever. I thought some thing wrong, after I asked the doc, the doc said is normal because the medication is fighting the bacteria in my body, that's why I have fever. Since the doc said I'm fine no need to worry much, no need to worry loh.
