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.

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.
