Thanks all for the advice.
Going by the above experiences, I think I’m lucky enough to have a ‘light’ dose of this condition as I’m not falling over. I went to the kids club night last night in an effort to get on with it. Initially riding a bike felt very ‘detached’, but it didn’t take long to feel right again. The slow stop-start nature of a kids ride probably helped too forcing me to work at it. Good job it came right too as it was steep descents last night and I didn’t fancy binning it into the trees.
But got home and felt dizzy again once inside. Being inside seems worse and screens definitely don’t help either, although I do need to work today, so just have to put up with it. Dizzy now.
edit- not taking the drugs either.
