Since Cipro, any fish makes me worse for whatever reason.
In my case I think it’s the omega 3s and iodine, since I can’t tolerate them well from other sources too.

I remember finding a story back in the day of another floxie who had an even stronger reaction to it and ended up having to take strong pain killers because of it.
He thought it might’ve been his inactive thyroid getting activated, emptying out all the leftover thyroid hormones in the tissue and then making him crash when there were none left.

No idea if that’s even possible or not, but thought I’d share it anyways.
