Narcolepsy
"I have been taking Ritalin for my narcolepsy for almost three years now. It helps significantly and without it, I don&#039;t think I would be able to work or function. However, my dosage has needed to be increased as it seems my body is getting used to it. It&#039;s also a great alternative to Provigil because it does not interact with birth control pills as Provigil does."
