I also was diagnosed in '98; I had already been sick for about 15 yrs, just not a fan of doctors. My diagnosing neuro advised against meds, saying that they have awful side effects, including osteoporosis. He sent me to a naturopathic doc, who advised me about diet, nutrition, allergies. I've never taken disease modifying drugs. I have read in many articles in various ms magazines which said that with this disease, progression is happening even when one is not experiencing exacerbations.
At the beginning I thought I was going to beat this. All went well enough for the first 8 yrs, but things are progressing for sure now. I do have a friend with ms who was avid about taking her meds. A lawyer. Another friend, who worked with her on the county mental health board, told me that she had lost her office. I emailed her to find out what is happening and learned that she is now is an assisted living facility after losing her practice, office, home. So there is no guarantee, no matter what you choose to do.
I wish you the best of luck. And now there is an alternative (CCSVI) to explore. You can read about the people on this site who have had their CCSVI treated. Click on forums. There are several threads on the subject.
