Metronidazole
"I feel horrible. I have one more day left (I was prescribed Metronidazole intravaginally for five days) and amen to that. Although it has worked wonders and gotten rid of an infection I've had for years and could never completely eradicate, these side effects are HORRIBLE. I've been dizzy, have had terrible headaches, eye pain, aches all over my body, absolutely no appetite (I'm repulsed by any food!), when I force myself to eat I get sick immediately after, gnawing stomach pains, pressure-like back pains, pain in my actual ovaries, grogginess, constantly tired but sleeping is beyond difficult (I somehow managed four hours last night), when I do sleep it's not refreshing at all, and exercising is practically impossible."
