Stomach bug

Any recommendations on how to get to feeling better with a stomach bug? I am 7 weeks and woke up in the middle of the night hysterically vomiting, I have been sick all day and finally have been able to hold down fluids starting about 2 hrs ago. Any remedies? Or tricks that you think could help would be greatly appreciated! I have been laying down most of the day, getting up makes me feel worse ugh. I do have a two yr old so I have had to figure out ways to keep her occupied while running to the bathroom off and on. It started at about 1 am and has not stopped since :/
