I got diagnosed with MS and I take it for my muscle spasticity at night to help me sleep, so it's completely unrelated. I have -20 vision with severe astigmatism and was completely uncorrected until I had eye surgery at 4 to fix some eye muscle issues. It reverts when I don't take the drug, but I can visualize a little bit whereas I used to not be able to 'see' in my mind at all. Like right now there's none in my system so I can vaguely imagine an apple as a red, roundish object, but not more than that. I read to fall asleep, and I noticed when I started 'seeing' stuff in my head in addition to 'hearing' it. I do wonder if it's connected to the fact that one of the side effects at high doses is hallucinations, which I do also experience.
