I filled my husband's glass of water up with laxatives
I don't know why you would do such a horrible thing. Was it really necessary?
Yes, he made me angry and he totally deserves it
No, no one deserves to get their drinks spiked with anything at all. It's malicious, betraying, and harmful in the end. Using laxatives improperly can cause a lot of internal distress, it's not just going to the bathroom often.
This is none of your business, he made me very angry and I want to hurt him.
You should not seek revenge on your husband like that, it can be very dangerous. Talk with him about what made you so angry and try to fix it in the future.
