For me, the first day I took adderall, the world changed. I stop struggling with where I left things, started to remember the things I needed to do when I got home without the help of an app, it was like a light switch had been flipped. Sadly, my blood pressure doesn’t like stimulants and I had to switch medications.

I have been on Strattera for many years now. Every now and then I find myself thinking it is not working and I decide to stop taking it and my life gets 10 times more difficult.

Obviously what happened to me may not be the typical scenario, as there are many different aspects of ADHD, but from my experience if in 21 to 30 days you do not see improvement on your ADHD symptoms, might be time to try a different one.
