I have severe ADHD and have had it as far back as I can remember. I did not begin taking the meds for it until I was in my mid-30's...and what a difference it made! I am almost 50 now. The clarity, the ability to finish a task!! Being able to read an article without scanning to the end first... It enabled me not sit in a straight back chair rocking and moving like a whirling dervish! And so much more.... It was SO worth it to me. Everyone is different but I would recommend trying out a few to see if they might help YOU.
