Persistent Headache...

So I have been trying the 80mg a day since Sunday and have been fine until today. I have had an extreme headache that won't go away. I talked to my sister (who has taken Accutane too) and she said it probably from looking at a computer for 8+ hours a day a work combined with the Accutane. I'm going to try and limit my computer activity at work tomorrow and see what happens. If it doesn't go away tomorrow I'm going back to 40mg a day.
