I just Finished up testing for SPD and despite sleeping well last night, I spent the first half of the exam feeling sluggish and groggy with slightly stunted cognition. During the break I had a cup of water and my mental energy shot back up to 100 percent within minutes, and I breezed though the vignettes like nobody's business.
DON'T BE AN IDIOT LIKE I WAS. Walk into the testing center properly hydrated.
(Fingers crossed on the results because I need to)
