Modafinil and Provigil are stimulant-like drugs that are mainly used for narcolepsy and shift work disorder. However, it has been used off-label for things like ADHD, fatigue, and even as a cognitive enhancer.

I would recommend Modafinil (generic provigil) as it is cheaper and they are pretty much the same drug except their chemical structure is a little different.

It would definitely help with your fatigue as that is their main function. However, seeing as you are already on a stimulant, Concerta, your doctor might be hesitant to prescribe this on top of it. That just depends on your doctor.

If your heart is fine and they know you have a problem with excessive sleepiness, then they probably won't have a problem prescribing this to you.

As I said earlier, these are also considered "cognitive enhancers." Some people use them like adderall or Concerta and they get a boost from these drugs in school or work due to the energy and the increased focus and concentration.

Any other questions, don't hesitate to ask!
Hope you're doing well!
