I just had three bouts of diarrhea. I checked my temperature and it was 101.5 degrees (38.6 celcius.) I'm feeling extremely weak, dizzy, and lethargic. I have upper stomach pain and intestinal cramping, but no nausea. I took three activated charcoal capsules to stop the diarrhea, so I can't take any other medications for two more hours. I don't have any anti-emetics as I'm staying at my moms house tonight. The only thing I have is Benadryl (diphenhydramine.) I can't go to the store for any other medication or go to the kitchen to look for something to help because my mom is a really light sleeper and gets upset if I wake her. I'm really scared this is a virus. Is there anything I can do with the limited supplies I have to stop this?

I don't know what I could have picked up because I am constantly using norovirus killing hand sanitizer and I don't put my hands on my mouth, nose, or eyes. I'm scared and need help.
