Is Taking a cognitive enhancer before the military asvab considered cheating?

I am scheduled to take the ASVAB exam next week. However, I do understand that I am ADHD. I haven't taken any medications since high school, however, given that I want to perform well on the upcoming exam, I am tempted to take a few of the pills that I have remained. Unfortunately, I do understand that my prescribed Ritalin has been considered as providing some with an unfair competitive advantage. I was told that when I take the exam I will be competing against others who I will be texting with. So once again, is it considered as cheating? If so, I will just continue studying for the exam and try my best to focus on the matter at hand. Any tips would be appreciated.
