Anyone know if this will cause permanent damage...?

Heres the thing...Swim has been taking ultra small amounts of meth to stay awake for about 2 week (but sooooooo little it's almost not even worth mentioning). Swim has pretty bad narcolepsy. But to be honest swim doesn't really like it very much. It just makes swim too nervous about permanent damage. swim wont be buying it again, she will find something else to stay awake. swim has roughly $35 worth left. Is this enough to cause damage if she does does it in regular amounts until it is gone (a few days). Will less than a week of "moderate" use cause any permanent brain damage in the dopamine/cognitive areas? Anyone have experience they can share with just using it for like a week, give or take?
