Hello, had anyone here try modafinil? the pill that can make us increase our mental focus and alert for a long time, well its main purpose is not for cognitive anhancer. but for off label use its can increase our focus. for me its hard to gain focus in this techo life with smartphone, computer etc..i try to make my butter coffee, but not as good as bulletproff coffee. if anyone have a same passion like me come and share your story
