Quite a few:
- Suddenly I didn't need to rely on last minute panic to get boring stuff done: I could just think "this needs to get done"...and do it. I could clear my whole chore list without taking a break every 10 minutes to hype myself up, then go play games for the rest of the day
- I could write a to-do list and actually remember where I put it, and I could even manage to read it!
- My reading speed tripled since I wouldn't keep losing my place every 15 seconds.
- I wouldn't fall asleep just from sitting still for too long.
Corny as it sounds, after taking a long hiatus from treatment and then starting up again, I felt like I turned into Superman.
