Shift Work Sleep Disorde
"Works pretty good but doses only cover 8 hrs.  Because my shifts start at 5 am and can end anywhere to 8:30 pm, I have to guess at my 8 hr. Window.     When I take 1.5 pills per day, I run out too fast and the pharmacy holds the script. Then I crash for several weeks until refill.  Nuvigi and provigil are true wonder drugs but I personally need 250 and 125 simultaneous as we go into a 24/7 society, I need covered at least 12 hrs."
