A member asked:
For a longer effect is it better to take 100mgr of modafini in a single row or is it better to split it into 50/50mgr throughout the day ?
A doctor has provided 1 answer
Recommend morning: Modafanil has a 15 hour half life, meaning that 1/2 of the dose is eliminated from your body by metabolism or excretion every 15 hours. The clinical effect is long enough that once in the morning dosing should be sufficient. Splitting the dose and taking half later in the day could interfere with sleep. That being said, It would not hurt to try the split dosing to see if that works better for you.
