punctuation - Using colons and semi-colons in dialogue

I've often heard writers say they don't like using colons and semi-colons in dialogue specifically and I don't often see colons and semi-colons in dialogue, but sometimes it just seems like it's by far the best option.

For example:

"I told you: John doesn't work on Mondays."

Is there any real alternative to this?

"Don't worry; I only get drunk on Sundays."

Is the semi-colon ok, or is it awkward in dialogue? Putting a full stop after Don't worry seems strange to me.

"I’ll do anything it takes: rehab, counseling, therapy, whatever I need to do.”

Is the colon ok here or is an em-dash better?

"It's an article about all the types of things you hate: the environment, animal rights, veganism, that kind of thing."

Is the colon above ok in dialogue?

"Trust me; the WASPy stuff is nothing in comparison."

Is a semi-colon appropriate above? Once again, it seems strange to me to put a full-stop.

"Those things I said—I didn't mean a word of them."

Is an em-dash appropriate here? I thought you weren't supposed to put a full clause after an em-dash if it finishes the sentence? If so, should I use something else like a colon?

"I know you; that place would haunt you."

Is there another way of doing this?

Thanks so much for any advice! Please note the question is specifically about dialogue.
