Speed…

I think amphatemines are what we used to call speed in the old days. I remember back in college the girls who lived upstairs used to take that to lose weight & they would run up & down the stairs continuously. My opinion is that your neuro is taking the wrong approach.
Trying to keep you awake when the body is exhausted (I call it “hitting the brick wall’) is very counterproductive to CIDP. You are tired because your nerves/body is worn out; it needs sleep to rejuvenate. I think it would be better to take something to make sure that you get at least 8-10 hours of uninterrupted sleep, thus allowing the body to rejuvenate. Maybe trying Ambien, Lunesta, or even Xanax at bedtime might give you the sleep pattern you need. My opinion, stay away from the amphatemines if you have CIDP!
