I just thought I would give an update and give some hope to others...
2 years ago I thought that this is as good as it is going to get but things did still improve considerably in the last 2 years.
My balance improved to most in the last 2 years, I still get those mornings that I wake up with an unbalance but these happen less frequent and recover in a couple of days where it used to take weeks.
The fatigue reduced slightly and my memory improved quite a bit, still not what it was before the operation but a lot better than 2 years ago, I still take a nap if I can when I feel tired as this always helped.
As to the eye watering, my nose running when eating and the eyelid not closing completely these have not improved but putting eye drops 6 times a day and eye gel for night time helps.
So yes, things still improve after 2 years, just be patient and don't be to hard on yourself, give your body the rest and time to heal...
Thanks to the forum and it's members, I found a lot of useful information here and much needed motivation to keep me going in the last 4 years :-)
