Modafinil vs Flmodafinil, a terrible headache NSFW

First, let me share my experience with modafinil. I made 300mg pills. And I took it at 6:00. Then within a hour I was pretty wakeful and focused, my head was clear. My day was great, I was feeling like a human, without the tiredness i normally experience.

Then I tried Flmodafinil, I thought 75mg would be great starting dose. Within a hour, I developed extreme tension headache and muscle twitching. It was so terrible NSAIDs weren't helping at all.

Does Flmodafinil tend to cause more headaches than regular Modafinil? I thought fl was supposed to have lesser siide effects.

Yup. Stay hydrated and well fed or headaches & nausea will hit. Classic provigil & nuvigil side effects. Can’t speak for flmodafinil
