Hi wmc, good idea, I have tried the sea bands but they didn’t help either sadly.
I’m most likely on the autistic spectrum but unable to get a diagnosis due to my verbal issues ironically. I can type all day long but struggle to deal with people face to face or on telephones which has ben a huge barrier to any medical help so far. I have written letters for my GP recently which didn’t really work but may try one to the optician as suggested.
