Looking for advice on Sertraline withdrawal symptoms

Looking for someone who may have had a similar experience following on from reduction of Sertraline for Anxiety. Having been on sertraline for over 9 years I had decided that I was well enough to reduce and stop taking it. Unfortunately, after a very slow reduction that spanned several months, I started experiencing symptoms of swaying/rocking sensation internally and also feeling as objects I was looking at were also swaying. After spending several months trying to figure out what was wrong, eventually came to the conclusion that it was the reduction of sertraline that was behind it. Hoping that others that may have been suffering from something similar may be able to give me some tips!
