Doc,
Take Cipro for serious Montezuma. Take a suture kit and some lidocaine- somebody always seems to slice something. General antibiotic and analgesic of choice. Toradol 10mg works wonders on everything including hangover.
Diphenhydramine, sun screen and bug repellent. Tsetse are the worst. Some golf or baseball batting gloves will save you hands from tsetse and thorns if you run into either. Fingernail clippers.
Wish I was going with you, but have a cold one around the fire for me. Also, enjoy Sharpe's stories. Amazing, they are.
