Did you know that I've been taking my son's ADHD medication and now I think I'm addicted to it?
That's crazy. Why did you start taking your son's ADHD medication?
I've had so much work to do and the medicine helps me focus and complete all of my work tasks.
It's wrong to take medication that was not prescribed to you because it can be dangerous and addictive. It's unfortunate that you are so stressed at work, but taking medication that's not yours is not the proper way to handle the situation. Talk to your doctor to see what he suggests for you to do.
I've been taking it off and on ever since I got it but this time I'm going to quit for sure.
Yes, please quit it as soon as possible. It's not fair to your son because he only has a limited supply and he needs it. If you ever have trouble quitting and need a boost of strength, just think about how much these drugs help your son to get better.
