After I swallowed 2 pills (panadol), I felt nothing,meaning it doesn't work. But I felt okay when I woke up in the middle of the morning, around 5. Just 1 problem, my throat was worse. It's so pain to swallow but I still can talk. I am still feeling dizzy today. Usually, the dizziness will only last for a day but it has been for 3 days!!! I starting to worry if this will last forever... haha!!
