Living with ADHD often comes with a complex medication journey. While stimulant medications like Vyvanse can significantly improve focus and executive function, they also bring unwanted side effects—particularly dehydration. For many adults on ADHD medication, staying properly hydrated becomes an unexpected challenge that can lead to serious physical symptoms and discomfort. The good news? Sometimes the simplest environmental modifications can make all the difference.
If you’re taking ADHD medication, particularly stimulants like Vyvanse, you might have noticed increased thirst or dry mouth. These aren’t just minor inconveniences—they’re warning signs of potential dehydration.

‘I’ll be working on a project, and suddenly I realize I haven’t had a sip of water in four hours,’ shares Michael, a software developer who takes Vyvanse daily. ‘By then, I’m already experiencing a headache and muscle cramps.’

Why can’t people with ADHD just drink more water? If you’ve asked yourself this question, you’re not alone. The challenge isn’t knowledge—it’s implementation.
