Travel Medicine

This is the first time I've ever traveled to a destination that actually requires me to know something about travel medicine. In Mexico it was basically don't drink the water and don't buy food off the street, orders which I followed to a T and never had any kind of problem. Thailand is different. First off, I'm getting a bunch of shots before I go, including:
-a polio booster (this not recommended by the CDC, but IS recommended by Group Health, so what the heck, better safe than sorry)
-a diptheria/tetnus/whooping cough booster
-a typhoid vaccination

These shots make me feel as if I am about to travel the Oregon Trail (You have Typhoid! What would you like to do: a) administer laudanum b)rest for two days c)do nothing)

I'll also be carrying with while in Thailand two prescriptions, one to treat "severe gastrointestinal distress" (because I'm basically seven in a lot of ways, I find this both gross and hilarious) and one to take while I'm in Cambodia and for four weeks following to prevent malaria. Not to mention as Pepto-Bismol (8 a day!) as I can fit in my suitcase. Lonely Planet tells me I can eat the food from street vendors, much to my delight, but I imagine it can't all be a hundred percent safe.

Then there's the question of preventing bug bites....
