If I was Diagnosed with ADHD should I take medication for it?

Have you had a SPED evaluation from the school? I was totally surprised at how significantly ADD was impacting my daughter. When observed unmedicated in class - she was paying attention only 60% of the time. Zoning out 40%. (Depending on the class - the rest of the students were paying attention 90-95% of the time).
The reality of that observation hit me like a ton of bricks. My then sophomore daughter’s brain was absent from class 40% of the time. How would her grades be if I kept her home 40% of the time? Yes she could cope - but it was a struggle and made high school unbearable.

She opted to medicate only for school. Not weekends and not summer. And she is on the lowest dose she can be on and still see benefits. She does not like the way it makes her feel slow (which is means it is actually doing what it is supposed to). Her grades have improved tremendously and she doesn’t hate school anymore.
