I have severe sleep apnea. My neuro is the one who suggested the sleep study when I was complaining of fatigue. I was certain I didn't have it, I don't snore and in my mind I just couldn't imagine that I would have to deal with one more "problem".

So I humored him and took the test. Was I ever suprised to find out I had it. I now sleep with a CPAP and feel so much more rested when I wake up. I hated it at first but you get used to it.

I don't know if it is caused by my MS, that has never been suggested. I could stand to lose some weight which I've been told can take care of it. But my SIL, who is thin, also has it, so who knows?

If you dr wants you to do the study, I say go for it. Good luck!
