It’s more than just ‘triggers’. I believe it’s fundamentally Potassium restriction to influence the fluids in your ear and improve the balance. Long term this might form part of an actual cure unless there are exacerbating factors that don’t resolve (eg a fistula). As such strict adherence is really worth a try and is probably much better for you than long-term use of a diuretic.
