I'm glad I've turned you on to something new :-)

Although I would say that I'm not sure if it is technically a stimulant; I believe it works by blocking certain neurotransmitters that cause drowsiness and at the same time, woolly thinking.

As far as meditation is concerned, yes it does help, though I was into meditation before Modafinil, and I learned various tricks and techniques to stop my wondering mind.

Check out my article on flow state https://steemit.com/incredibleyou/@cryptogee/incredible-you-finding-your-flow-state-superpower and the Incredible You! series as a whole.

In that series I talk a lot about using meditation to get you into a state whereby everything flows for you. I give lots of tips for how to meditate.

The main thing to remember is that meditation is a test of will; your mind is supposed to wander. It is about how you react to the wandering.

Meditation doesn't stop the voices in your head; it just helps you ignore them :-)
