i am an addict 2

I have been very tired lately, I think it is due to too much travelling. Yesterday was one of my worse days in office ever. Lately I've been trying to kick off my caffeine addiction habit and have been quite successful and have reduced to one cup a day during lunch and for the rest of the day drinking green tea as a form of "nicotine patch". However yesterday, I had a relapse, a very bad one. 7 cups of coffee and 2 cans of coke in order to function at minimum level. Somehow the green tea just didn't cut it yesterday and had to resort back to good old caffeine in order to stay awake in the office and to stay alert enough to make positive contributions in my meetings.

It is only 11:50am now, and already I am at my 3rd cup of coffee. Sometimes I just wonder, is coffee really that potent to help keep you awake or is it a psychological thing that was in-grain inside me since I was young that "coffee helps keeps one awake". I was thinking, if my mom in-grained in me that "water keeps one awake", would water really make me feel awake? I know if I splash water on my face, it does help a tiny bit. So is it psychological? If it is, from tomorrow onwards, I am going to tell myself "water keeps one awake", but than the thing is when I think water I think of this:

yes it looks refreshing, and you should feel awake, but when I see this, I think about the sound of the waterfall and the midst form by the water splashing down and this makes me sleepy. I think I'll declare a work from home afternoon. Hope everyone doesn't feel as lethargic as me.
