The lighter side of ADHD
Image not quite for ADHPeeps but I feel this sort of thing happens regularly for us as well.
My exam trick was no coffee for two days before the exam, then a couple cups the morning of. Worked great. In other news, holy crap, do I have ADHD??
I'm also from a family with low blood pressure. And sugar is a great trick when it falls down even further. It also help me to study longer but it is hard to strick the right balance with extra-energy and reduced concentration.
I used to be the one weirdo who could shoot an 8 ball of coke and be perfectly calm, at least for a few minutes until it started to wear off. That was a long time ago, and I was just diagnosed a couple years ago.
