Not at all. You can take Ritalin and Adderall, but that will give you the personality of an accountant and take away your creative problem solving skills.

I managed to take a low dose of l-amp for exactly 2 consecutive days before I started abusing again. Yes it worked, but I just want more and more. You feel like a superhero compared to baseline.

Never mind..
