If you can wait to start until the long weekend, that is always ideal. That way you can start on Sat. morning, tweak timing on Sunday morning, and have Monday for more tweaking if needed before school on Tuesday. Also talk with your kid about a plan for how and when you’ll discuss how they are feeling while doing the trial. I would do a couple of planned check-ins to see when it kicks in and when it fades out.

Would you prefer to start the medication on Friday or Saturday, just to make sure there aren’t any side effects?
