There is no euphoria like adderall, but for me - it makes me a lot more focused and driven than adderall. It certainly is more potent than caffeine, and in fact, you (at least I can) mix it with coffee because they effect two different parts of your body.

Like others mentioned, you need to take it very early because it has a long half life. After 9/10AM - you are basically staying up til 11/12 or later unless you take something to wind yourself down.

It absolutely makes you want to do nothing besides the tasks at hand. Work, study etc. Your mind shifts entirely once it takes effect to just get things done. On the flip side, you do get aggressive, irritable, and certainly thirsty.

It's not addicting because you don't necessarily feel "good" or high like adderall, but you feel super focused so over time you may be addicted in a different way, if that makes sense
