I don't have much advice as I have not had ON quite that bad. But, I can offer you lots of 's.

As for the sleep disturbances, I have heard of people, with or without MS, who have experienced that. It sounds horrifying and very scary and I don't blame you for not wanting to go back to sleep. This needs to be addressed with your physician. What medications do you take? Is it possible it is one of the medications?

I agree with the others that getting a second opinion would be a good idea, even with another PCP, one that will give you a referral.

Hang in there Anya! Let us know how you are doing.
