The symptoms you describe are very similar to my own. Following a bout of Optic neuritis and an MRI I have been diagnosed with Clinically isolated syndrome which will convert to RRMS in the event of another acute attack.
In view of what you describe I would advise as a precaution
Start taking high dose Vitamin D now. At least 2000iu and get plenty of sunshine too
Fish oil would be helpful
Adopt an MS friendly diet - plenty of oily fish, cruciforous vegetables, olive oil, nuts, fruit, liver if you can stomach it.
Consider Gingko Biloba supplements
