I am well and truely an adult, and have been for longer than I care to remember and I really struggle to tolerate the stuff, so 'adulthood' along doesn't confer tolerence to the stuff.
I am really really sensitive towards any drugs that push my brain around at all - I have always thought that is probably because my brain is so compromised by my lupus that provigil (and a whole bunch of other drugs) are just way too much for me.
I think some can tolerate it, some can't, and I don't know if there is an awful lot that anyone can do about it. I have never yet been able to fall asleep unaided on the days that I do take it - I always have to use sleeping pills to knock me out if I have taken it. Definitely gives the the jitters x 812 if you know what I mean.
It helps me to go to work when I am desperate and really need to go in (usually meetings I just can't miss, stuff like that) but there is no way on earth I could take it on a daily basis.
hope you find a way to make it work for Alex
