I thot I posted a reply earlier this week but now I can't find it, so maybe it didn't work. My computer is acting up...
Ok, will try to make it succinct. I'm the one who voted for acetlyl l carnitine (ALCAR). Unfortunately, my circumstances are such that I don't know what's impacting what so can't be of much help.
I'm on Avonex 3 months, 3 days before I did a round of oral steroids for my first relapse, I began taking compounded HRT, ALCAR and alpha lipoic acid (ALA).
The pharmacist recommended the ALCAR as neuroprotective and the ALA for the numbness, burning, MS hug of left leg symptoms. (It really seems to be working.)
I am taking 1/4th the dose (500 mg day) of the ALCAR used in the Italian study (1 g 2 x a day if I remember correctly.
Overall, I'm feeling much better and definitely more alert.
Since you are struggling with this, you might consider trying the ALCAR at the recommended dose before you see your neuro. ALCAR is readily available over the counter in the US, so I think it would be in Canada too.
Maybe by the time you see him you'll know if it's working
Good luck and let us know what you decide.
