"i definitely noticed a difference while taking strattera. the symptoms of my adhd have improved indefinitely. i feel less withdrawn from reality, increased self esteem and better focus. the 25mgs gave me insomnia. with the 40mg i stopped noticing the benefits of strattera and noticed more of the side effects (dizziness, hot flashes, etc). 60mg seemed to be the most effective for me. but after a week of taking the 60mg, i didn&#039;t go a day without nausea. the nausea was so bad that it practically cancelled out the benefits of strattera. this is just what happened in my case. i would recommend this medication in hopes that the side effects aren&#039;t as bad for others."
