Optical Neurologist visit tomorrow!

December 18- I am going to an Optical Neurologist tomorrow. This will be my first visit with a neurologist of any kind. I am a huge mash-up of emotions. I am excited to see what they may come up with. But also completely freaked out. What if they find something crazy serious. But also, what if they find nothing at all.... Ugh. I just want it to be over with already. I am to expect to be there at least 4 hours, although it could be more! Any of you see an Optical Neurologist before? What kind of tests do you think they will do that it is going to be such a long day? Send positive thoughts and prayers my way, OK? Thanks guys! xo
