Really? Never tried.
Already did Ritalin pre-workout some times.
I heard that Modafinil doesnt hav the aphetaminic/euforia effect.
It's much better than Ritalin IMO.
That's what makes it good, there isn't that stimulant effect you get with Adderal. It's a smooth energy that feels more like a caffeine high. I get the increased energy and intense focus, then I can easily relax and sleep that night. It's a win / win. I do get burnt out on it if I take it for a while, but I typically only take it a few times a month, 50-100mg in the morning with my coffee.
Nothing like getting up at 5am popping some Prov, work 12 hours, go to the gym for 1 hour and home in time for bed by 9pm. When you work long hours, it's an incredible drug.
