My shower goes from hot to cold all the time and every time it does I yell at it. I live in an apartment and my neighbour must wonder about me. But I'm sure his shower does it too, so he probably laughs when he hears me.
And I mutter bad words under my breath every time my laptop misbehaves.
Everyone does things like that from time to time. Don't beat yourself up. It's human to get frustrated. Yelling or swearing at inanimate objects is harmless.
Just don't take any more advil. If you haven't already, eat a meal, or at least some milk and bread to put something into your stomach beside the advil. Eat some soothing foods, like eggs or oatmeal. Did you phone poison control? If not, phone them to put your mind at rest.
