narcolepsy
"I was just prescribed modafinil and I was happy I picked up my prescription on Friday so I had the weekend to try it out. So yup- I woke up and cleaned things I haven't cleaned in months with incredible focus. I didn't feel scattered, didn't lose my train of thought, my attention span was excellent. It almost made me wonder if I had ADHD and never knew it. But anyway, I took 100mg, half a pill at a time. No headache, no nausea, I ran a couple miles and did okay. I was able to feel good and not be tired and even got to play with my kids in the evening- something that never happens because I'm usually too exhausted to do anything like that. Overall, I'm feeling a ton better!"
