I wake up with a sore jaw on Vyvanse. Side effect or just stress?

Waking with a sore jaw on Vyvanse can be stimulant-related tension for some people, stress-related clenching, night-time bruxism, or a mix, and a forum cannot pick one. Vyvanse is lisdexamfetamine, a stimulant used for ADHD. NHS information on methylphenidate, another stimulant class used for ADHD, lists psychiatric and neurologic discomfort and related tension among effects some people notice. If the change is persistent, distressing, or affecting daily functioning, bring a brief timeline to the prescribing clinician rather than changing the dose independently.

Stress was my first story as well, until my partner said I sounded like a coffee grinder at 2am. I felt embarrassed more than scared. I started a two-line sleep note, sore or not, so I was not guessing in the appointment. The jaw still has loud weeks. I would not treat my nights as a reason for anyone else to change their morning capsule.

I woke up with a sore jaw for weeks after I started Vyvanse and blamed a stressful month at work because I was clenching in emails too. I bought a cheap mouth guard from a pharmacy and then actually went to the dentist when a molar felt cracked. I told the prescriber the morning timing. I did not drop the capsule myself. This is only my teeth, not a split between stress and medicine I would make for anyone else.
