Few weeks never experience this kind of weirdness le. Today it came again. All because of a small(really small) cup of coffee. I made a mistake to drink coffee in the office. Very fast...the weirdness came very fast. My hands trembled...and felt cold. I mean only hands cold not whole body. But lucky (maybe due to small volume) the weirdness subsided after i ate and drank more water. I hate the weirdness...next time no matter how tired i am in office, i must tell myself not to drink coffee le. Must have determination...Sometimes i am wondering if i experience this weirdness because i am paranoid???
