I'm trying to cut down on my coffee intake and decided that the best way to do it was just to go cold turkey and stop drinking it completely. From being super sensitive to caffeine, I imbibed so much coffee during the weeks leading up to my event that it took 2-3 cups to give me the same effect. Not good, not good at all.
So now I'm glugging green tea, which I know has caffeine, but not as much as coffee (I hope) and it's anti-oxidant properties will be beneficial too, I guess. One tea bag of green tea lasts me the entire day and all I need to do is top up the hot water in my cup.
It's been half a day and I've been yawning quite a fair bit, but it's manageable. Let's hope I can last the day. *grin*
