Contagious stomach virus?

My kids had this bug and it lasted them about 12 hours. I woke up early this morning with it and I need to find a way to stop it fast. I used to be a healthcare provider so I'm well versed in hydration, rest, brat diet, and still had some zofran. That aside I'm miserable and I need some homeopathic suggestions for helping with the nausea and bowel issues. I'm home alone with my young kids, and I was supposed to clean the house for my parents flying in tomorrow. Zofran and ginger ale aren't helping.
