Caffeine Overdose

This morning before I left the house I had a large cup of coffee. My boss asked me to come 30 minutes earlier than usual because we need to do some brainstorming on one of our new machines. To thank me for coming early, she bought me a large cup of coffee. Around 10 am, I was starving. So instead of eating junk, I bought a cup of coffee. 12pm I had my lunch and I bought a coke to drink, then coffee. Then around 3pm, my co-worker bought coffee for everybody. Then around 8pm, I had coffee with my husband. Now I'm feeling a little bit dizzy and I feel like throwing up. Was it because of the caffeine overdose, who knows? But one thing is for sure.. I don't want to drink coffee anymore... well at least until tomorrow.
