I know what you mean with everything revolving around your butt, especially with company over... Hopefully you're out of the woods soon.
If you do decide to start taking oral antibiotics, you should make sure to take the entire 10 day+ course of medication unless Dr. W Oks you to quit. Stopping halfway through if you are feeling better can let bacteria in your body develop immunity and return. Also, whats the name of the antibiotic? Some antibiotics that target your GI tract can give you wicked diarrhea; you can google "antibiotic associated diarrhea" to see some info about it. I only know from experience from a few months ago when I thought I was really sick after taking an antibiotic called flagyl- I've since read of others with the same experience. I read that if you take some probiotics and/or yogurt it can help restore the normal flora that are suppose to live in our bellies. -just a thought.
