I noticed the location of North Carolina. Is that kinda near Fayetteville by chance??

Best thing I have done in the past is get all the shots in advance, and talk to a doctor that can research the region. Then I kindly ask him for advance scripts of anything he might find useful, along with good written instructions as to what's for what.

I also start taking Pepto twice a day three days in advance of leaving, continuing until three days after I return. It seems to coat the tummy and let the bugs slide on thru.

You could also make friends with an SF 18D (Medic). I promise they can steer you in the right way.
