I was once hooked on the brown and evil substance.
I couldn't study unless I downed pots of coffee, fizzy drinks and Wake Ups tablets.
I cut down gradually since then (no Wake Ups since the last uni exam and no fizzy drinks for the last several years).
Few years ago, I decided to go cold turkey and give it all up. I spent a weekend with a pounding head and feeling queasy. But immediately afterwards, I noticed the difference: no unexplained stomach cramps, shaking hands, jitter episodes and my skin looked ten times better than the dried up lining that used to cover my face.
It's different now. No more running round like a headless chicken at one in the morning because I had a cup too many during the evening.
