proceeds to play Mario Kart for 11 hours straight without using the bathroom or eating... Or writing that essay that was the reason for taking Adderall in the first place
ADHD drugs are weird. They help treat ADHD's symptoms well. However, they seem to induce something similar in normal brains.
Unfortunately, they don't give you motivation, they just make it easier to apply your motivation. Combined that with the loss of appetite and hyper focus can get impressive.
ADHD drugs plus ADHD means that I am bad about eating when I start to focus. When it’s really necessary, I prefer it because food slows me down, but for normal days it’s not ideal.
I always try to be in the process of doing the thing I needed to be doing when the Adderall kicks in. That usually stops me from looking at the clock and realizing it's been a whole day and I've been doing something stupid.
