Yawn-o-mania

I have a question

What is the best yawn-buster? I’ve lost counted how many times I have to stifle my yawns, in anyway I could. Nose rubbing isn’t working anymore. I tried to bit my lips, but the nose blew my cover. I just could not control the ‘pengembangan lobang hidung’. Sigh. I do not want to appear rude to whoever talking/explaining/briefing me at that time. How how how? Bukannya boring kat sana tu. In fact, what I have learnt so far will benefit me for the future, very interesting and valuable; but I just could not stop yawning. Coffee?? I was not a coffee drinker before this, but since I started attachment, that’s what I have every morning. And still… yawnnnnnn tak sudah2.

Penyakit betul lah ni.
