But, like many others, I’ve become too reliant on caffeine, so I decided to cut coffee out of my life for a month to see what would happen. November is a great time of year to try these little tweaks as there’s no external pressure to carry on (unlike new year when it all just seems… a lot). It’s worth mentioning that drinks such as tea and Coke also contain caffeine, but as I don’t drink either, this has been a caffeine-free month.

Caffeine is the world’s most commonly used psychoactive drug; it’s a stimulant that alters neural activity in the brain, improving alertness and reducing fatigue, and if you’re a devotee of the jitter juice, then the withdrawal symptoms will quickly follow giving it up.

“You may notice the effects of giving it up within just one or two days,” Dr Folusha Oluwajana tells Stylist. “Symptoms of caffeine withdrawal include headaches, tiredness, difficulty concentrating, irritability and tremors.”

Usually these will last just a few days, and the only way through these symptoms is, well, through them. But there are also more positive long-term effects that come from breaking up with coffee.
