Understanding what amplifies your crash is the first step to smoothing out your day.
Natural Wear-Off
Vyvanse typically lasts 10-14 hours. The 'crash' is often just the medication leaving your system—your baseline ADHD returning.
Sleep Debt Amplifies It
If you're not sleeping well, the crash feels much worse. Your brain has fewer reserves to fall back on as medication wears off.
Skipping Meals
Vyvanse suppresses appetite. If you haven't eaten, low blood sugar compounds the crash, causing fatigue and irritability.
Dehydration
Many people don't drink enough water on stimulants. Dehydration can intensify feelings of fatigue and brain fog during the crash.
Caffeine Timing
Caffeine earlier in the day can make the afternoon crash feel more pronounced as both stimulants wear off together.
High Cognitive Load
Demanding work or study sessions drain your mental energy faster. By afternoon, you may have depleted your cognitive reserves.
Dose Timing Issues
Taking Vyvanse too early or too late affects when and how intensely you experience the wear-off period.
Chronic Stress & Burnout
Underlying burnout makes every crash feel harder. Your nervous system is already depleted before the medication even wears off.
