welcome to the forum jen, and sorry to hear you've been going through a scary process while trying to plan a wedding
there are lots of folks here with a lot of different ideas on how to deal with ms. my own personal focus is nutrition, starting with a balanced healthy whole foods diet, and doing bloodwork to find out if additional supplements are needed. with ms, there are a known constellation of nutrient problems, they've all been identified and more or less researched in the scientific literature. have the docs done any nutritional bloodwork at all? usually they will maybe test b12, possibly test d3, often decide both are 'normal' and leave it at that. there's much more to it however! when you mention vision, my brain goes straight to zinc. zinc is on average lower in ms patients, and zinc status also affects the body's ability to utilize b12 and d3, by the way. chronic stress is tough on your system too, and when you're stressed, magnesium loss increases. magnesium is known to be lower in ms patients too.
zinc is also very important to liver health, and i just noticed a study on glatiramer acetate (copaxone) and liver damage, so you could be proactive there, since zinc has been shown to reverse liver damage such as cirrhosis. throw the search terms
zinc liver hepatitis
into google, and scan the studies that are returned.
anyway. it's a scary time but the more you read the more you learn and the more proactive you can be. if you're interested in nutritional stuff we have a couple different useful sections to browse (eg diet, natural approach) and my own personal spin (which involves some bloodwork) can be found on the first post of my regimen thread:regimens-f22/topic2489.html
once again, welcome to the forum, and happy reading
