Sounds like her dose is too high. If it were right, she could sleep without difficulty and the crash shouldn’t be epic. Overmedicating does leave to a behavioral improvement over properly medicating just like a normal person could abuse a stimulant to clean the house really thoroughly. That doesn’t mean it’s a good long term strategy. The right dose gives her the chance to choose to control herself. It doesn’t give her a MOTIVATION to do any task set before her. Overmedication does.
