Definately cant drive for more that an hour straight..modafinil 200mg plus a Monster energy drink and loud music..still the road noise can lull me to sleep...I actually have been in an awake but not awake state and woke up driving..had no idea where i was. Very scary.

Omg same here I live in DC metropolitan area there is always heavy traffic and I fall asleep in traffic going home and sometimes in the morning going to work if In did not get enough sleep or I ate something big. The diet is so important heavy meals make it so much worse. I hit the car in front of me as well. I have dozed off in traffic and have woke up from the car going sideways. Its terrible and scary! I literally slap myself and turned up the music to stay awake and that doesn't even work. I have explained this to friends and family and they told me that sometimes they get sleepy too. I think its crazy its the same thing. when I have drank 2 energy drinks and slept for 10n hours and I'm falling asleep at 9am going to work. Its hard people don't actually know what Narcolepsy or Cataplexy is. They almost think I'm making it up. My supervisor did not believe me until I brought a medical diagnosis. I quit my job and honestly I have anxiety of going back and dozing off at the job or driving.

All the time! Except I take Adderall.

I literally keep a blanket and pillow in my car

Whenever I am taking a trip of more than an hour, I "build in" an extra half hour. That way should I have that feeling coming on, I can pull into a convenience store and nap for about 20 minutes. Just part of my life now.
