I have 3 friends who have gone through MS testing, 2 had a positive diagnosis and one did not. The one who did not removed all artificial sweeteners from her diet and she stopped having the symptoms. The 2 that have MS are both long time "survivors". One is a child welfare worker (S) for the state and the other (G) has been an author of ADHD books, a licensed children's therapist, and a member of management at Wal-Mart.
(S) was diagnosed in the 80's and she decided she should put her affairs in order so that when she got in bad health she wouldn't be a burden on anyone. She bought a house and a new car, so that she would be pretty much maintenance free. Twenty years later she still has the car and the house. Her finance left her at the alter because he didn't want to watch someone he loved shrivel away and die slowly everyday...she got married a few years later to a wonderful loving and kind man and has had a wonderful life. She works every day and takes a medication regime that keeps her at her best.
My other friend (G) who has MS is a full time mom and active member of her community. She regularly takes her children to amusement parks and swimming activities, on island vacations and has regular fun filled days.
The one things she works hardest at is staying at her best by getting enough rest and not getting her body overheated by way of exercise, activities in the direct sun, stressing over stuff, etc...
Taking care of your body in a better way is something we should all do, it's the only one we get and we should treat it better. Just be patient and wait until you have the diagnosis. Then try the medication regime and find what works best for your body and take good care of yourself no matter what is going on.
