pelvic inflammatory disease
"I've been taking doxycycline for almost two weeks after being diagnosed with pelvic inflammatory disease. It makes you pee excessively and constipates you. But you will start to see the effects take hold within days. I'm now experiencing severe gas. I was nauseous in the beginning but that subsided after a week. Overall its a pain but it works. Don't lay down for an hour after taking it."
