Hi Sunflowers! Welcome to NT!
I was on a couple of the DMD's when I was first diagnosed. They made me feel worse than I already did. BTW.....double vision was my symptom that got me diagnosed, too.
Have you considered LDN? I've been on it for a couple of years and it's been a Godsend. Here is a link to the LDN thread here........
