Well, after a week of being so congested my teeth hurt I practically begged the OB today for ANYTHING that would make me feel better. She prescribed Zpack and I scarfed down the first two pills as soon as I walked out of the pharmacy. Has anyone else been on this? If so, how fast did it work for you? I'd like to enjoy the last days of my pregnancy (haha) and would prefer to worry more about keeping my BP down and LO in the oven for as long as I can. I can't even complain about how boring bed rest is because my face hurts so much.
