Describe a time when you felt extremely tired

I'd like to talk about a time when I felt completely exhausted, after a long trip back from a business conference abroad. It was about a year ago, and I had been away for five days. The schedule was intense: early morning sessions, long dinners with clients, and very little sleep because of the time difference.

On the last day, my flight was delayed by three hours, and when I finally got on the plane, I couldn't sleep, because the seat was uncomfortable and a baby was crying nearby. By the time I landed, it was already midnight, and I still had to take a taxi home, which took another hour due to roadworks. I think I'd been awake for almost thirty hours in total.

I remember that I could barely keep my eyes open in the taxi, and when I got home, I dropped my bag at the door, took off my shoes and fell on the bed fully dressed. I slept for almost twelve hours straight. The next day, I took a day off work, ate a good breakfast and went for a gentle walk to wake myself up gradually.

Being so tired affected me in many ways. I was irritable, I forgot simple things, such as where I'd put my keys, and I couldn't concentrate on anything. I realised how much sleep influences our mood and productivity. Since then, I try to build in recovery time after any trip, and I try never to schedule an important meeting on the day after I return.
