No side effects, maybe due to the fact my brain has needed such med. and years ago there was "no such thing as ADD", remember I come from the 50-60's era, so kids like me were labeled brilliant but mis-behaved or just daydreamed not paying attention at all.
The true and final test was with stimulants in college, I did excellent in so many ways.
Honestly, the only teeny side effects but can be confused with pre-menopausal symptoms, is dry eye and nasal passages. Soooooooooooo, I use eye drops and AYR gel,insert in each nostril with a q-tip, and things are fine, over non-medication for both disorders. I prefer dealing with the inconveniences (side effects) over the un-medicated symptoms.
But that is my own personal opinion. Everyone has to do what feels right as well as keeping them out of trouble, ha!ha!
I hope all works out for you.
