To those with experience, how has Modafinil use effected your own physical activity? Does it make it easier/more difficult to push harder in a workout, or does it not really have much of an effect at all in your experience? To those who do cardio, how does it effect your endurance? And what about strength training? Does it increase/decrease your lifts at all in any way, or effect your recovery time at all? Any and all input is appreciated. Thanks!
