I don't know this feeling. I never had this before.

Some of my colleagues in Dubai regularly go to the pub to drink after work, I don't go because I don't like the feeling after drinking. I only go when it is a team outing where we go to the house of our colleague, or go to the pub or sometimes on the yacht.  I drink occasionally, I got drunk before and the feeling is not good having headaches, dizzy, and vomiting.  

Last night I join with some of my colleague and their friends on a bbq night. I drink one and a half bottles of beer and all was good.  I got home well and sleep. I wake up roughly 11pm and I was feeling dizzy, with blurry images of things and my mind was randomly thinking of things quick, unable to focus, and uneasy. No headaches or body pain, it was like a bad dream. 

I was not able to come to work because the feeling was still there until 6 o'clock in the morning when I am supposed to start my duty. I can't even focus and unable to dial the number at work, that's when I notice my phone ringing and I got a call from work.  I sleep again and feeling better when I woke up.
