You know, i’m wondering if coffee acts like a diuretic on the ear.
The reason you feel crap might be that it’s changed the balance of fluids in the ear sufficiently enough to confuse the brain that got used to the previous set-up.
What’s interesting about that is it highlights something I’ve been thinking for a while:
Vestibular imbalance is caused by lack of compensation … for those with Hydrops as you get better, the Hydrops might well reduce but THAT will make you feel worse if it reduces too quickly as it will change the response of the ear too much and give you symptoms … so you think you are getting worse … but actually you are getting better - just too quickly!! Your vestibular symptoms, then, are more governed by the instability and the delta than the actual fixed amount of fluid imbalance.
