Evil Antibiotics

Okay no, they're not actually evil. Antibiotics are actually a good thing- in case you've lived ina cave for 50 years. And I'm glad I don't live in a mud hut with no access to them. But DAMMIT why do they have to make you so sick?
I'm taking something new for my bronchitis and sinus infection (oh and ear infection did I mention that one?) and among it's side effects are "Drowsiness, dizzyness, nausea...". Good god. Why do antibiotics have to make me drowsy and dizzy? The nausea I sort of understand, but the other two? Whose idea was THAT?
Combined with the decongestant I have to take, which gives me insomnia, I'm really enjoying this course of meds.
Better than being dead though.
