Question 1 Of I'm Sure 100s Lol So I've Been

Question 1 of I'm sure 100s lol
So I've been diagnosed with ms :( it's all good I just need to learn about this ridiculous "thing" so here goes.
I quit smoking Dec 2014 got diagnosed in March 2015 I have the kind that triggers crying (whatever that ones called). So I'm finally at a point where I wanna know what I can do to help myself!
Here goes.... What kinds of questions should I be asking? What can I do about the weight gaining? (That's a biggie lol) are there supplements I could be taken for the effects? Millions of questions I'm not even sure where to start so I guess thats enough for now. Thank you very much sincerely Kelly
