Stomach virus help?

I might have a "mild" case of one of these stomach viruses that are going around, any recommendations on what can help? I'm running a slight fever (around 99.2), get feeling nauseous in waves (no throwing up) and just feel run down and zonked. I've been sipping water with colloidal silver but haven't noticed any improvement. Might just need to ride it out and be more cranky than usual?
