This is just my opinion, but it probably is not a good idea to take the amphetamines. It sounds like your doc is another clueless doctor who doesn't now what to do with you, so she decides to shove amphetamines down your throat.

Others may be more knowledgeable on this subject than I am, but from what I have heard and read, amphetamines, which are speed, are not good for an injured brain. They are also not good for a body that has been traumatized. You could have some problems with your HPA axis and taking amphetamines will make that problem worse. Also, you had better make sure your cardiovascular system is up to snuff before taking these as they can cause heart attacks in people with weak hearts. They even came out with a study that showed people who used ritallin for more long periods of time were 65% more likely then the normal population to develop cardiovascular disease.

So, I would definitely proceed with caution on this one.
