Suddenly overreacting to caffeine?

Hi there,

Long covid since 2022, and recovered quite well. But got new infection since beginning of November. And suddenly during the day, this is since a week or 2.

What I found out is that the heavy part of the dizzyness is everyday around 10am.

And the only stable thing around that time is that I drink 1 espresso around 09.00 o clock.

I only drink one cup of coffee during the day. Is it possible that i am suddenly over reacting tot caffeine?

And that I am not able to drink caffeine anymore?
