24 and I have used adderral but only recreationally when I was in high school.
It will only be something that I will be using during work if I feel to spastic to keep concentrated on the project I am working on since I tend to get distracted by the smallest things and it throws me off.
And after knowing my doctor for 12 years I believe he will originally start me on Ritalin since it is the least addictive of the medications available.
