Stimulants and Nausea
“Recently, I’ve felt nauseated during the middle of the day and very tired by the end of the day. Could this be caused by my ADHD stimulant medication?”
I don’t have enough information to give you a definite yes or no. I suggest that you stop taking the medication for a week. If the midday nausea stops, it might have been caused by your medication, so talk to your doctor about trying a different one. If it does not go away, your doctor needs to explore other causes.
