So I take Unisom and B6 day and night, but I started vomiting this afternoon and haven't been able to keep anything down except for a few sips of water...don't know what the deal is. I dug up some Zofran from my first pregnancy, but it expired 2 years ago. Anyone taken expired Zofran? I think most drugs just lose efficacy over times, but I know some antibiotics get dangerous after they expire. Google is suggesting that Zofran probably isn't like that though. Thoughts? I feel God awful.
