# Tweet by [@keefmoon](http://twitter.com/keefmoon) on 2018-07-12 11:27:32 > [!INFO] Archived from [original tweet](http://twitter.com/keefmoon/status/1017369865198473216) I was once a week into working at a new office, new contract, and I couldn’t work out why I was so tired, nearly falling asleep at my desk. Was it not interesting? Had I made a mistake taking this contract? No, I had accidentally been drinking decaf tea from the office kitchen https://t.co/fQodlPiP2W
