So I take Modafinil because of Narcolepsy. 200mg daily. Have been for the last 13 years. I can tell you right now. You are setting yourself up to induce narcoleptic states, formication, possible schizophrenic episodes, auditory hallucinations, and last but not least, heavy dependency.
I know Modafinil is being used as a nootropic in certain places, but I do not recommend using it the way you do. It's all the time at the same dose or nothing.
It will take a while for these side effects to show up, so don't be surprised if it goes well for a while, then all of a sudden you find yourself swatting imaginary ants on your body when it starts to wear off when the half life of15 hours is reached.
You might start to hear people talking, only to realize that you're actually alone...
Dormant narcolepsy without cataplexy can happen and it's permanent.
Your mood will become unnoticebly irritable and swing up and down for no reason.
I urge you to reconsider taking this without a prescription. If you have one, follow it to a tee. Do not mess with this drug. It has ZERO recreational benefits. I only say it because I care.
