Okay so day before yesterday my daughter and my step mom woke up puking and they had fever and aching and hurting bodies. Seemed to be a 24 hour bug cause they're both more than fine now. Well last night i puked all through the night and now I can't even keep water down. Too scared to drink anything different or eat so much as crackers. I don't ache and I'm not in pain. I shake for a few minutes right after puking but that's how I've always been. Is it possible I just have severe case of morning sickness? Instead of whatever bug hit my daughter and step mom?
