I believe the answer is:

around the bend

I'm a little stuck... Click here to teach me more about this clue!

'gone this way in a tizzy' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'eccentrically unadorned beth' is the wordplay.
'eccentrically' indicates an anagram.
'unadorned'+'beth'='unadornedbeth'
'unadornedbeth' anagrammed gives 'AROUND THE BEND'.

'has' is the link.

Can you help me to learn more?
