Sorry charlotte885 but, despite you effort to correct your spelling, what you meant was
Dexedrine, no offense ;). You might be confusing
Dexedrine with Dexatrim and Dexatrim is a dietary supplement to decrease appetite with no stimulating effects like the stimulants we're talking about.
You are right about the drugs being in the same family, they are all psychostimulants mainly composed of amphetamine and/or dextroamphetamine, levoamphetamine,and other stuff like that...
