Hey Stilton,
Have been suffering from the same condition for over 5 months now. Looks like I won't be returnibg to work for another month at least.
Whilst I am still not 100%, my days of feeling better are becoming more frequent than the days of feeling crook.
I have had quite a lot of symptoms including tiinnitus, eye twitching, a spaced out feeling, and bouts of vertigo. My only recommendation would be to relax and accept the crazy symptoms. Unfortunately you won't find many answers to a lot of what's going on.
It truly is a very frustrating condition in both it's symptoms and the way it lingers for so long. I tried to find answers from doctor friends and via the internet and it just increased my anxiety making conditions worse.
There's one thing for sure and that is stress makes any condition worse.
Good luck mate.
