Don't eat raw vegetables or fruit unless peeled. Stick to peeled and
cooked food and you'll be OK. Maybe the spicyness can bother you a bit.

Fine if you don't care about nutrition. Health begins with raw, fresh food. People get sick in other countries because their body
has not developed an immunity to new bacteria/viruses. The smart thing is to stop all intake of food (no medicines/drugs!), and
fast for a day or 2. That's usually all it takes. Granted, this is not ideal on a vacation but its the only way to develop an
immunity to those different bacteria/viruses. That should be the last time you get sick once you have an immunity. You can't
possibly avoid the bacteria/viruses by avoiding raw vegetables. Its everywhere, on everything you touch. Are you going to walk
around in a bubble? Better to eat the freshest food possible to keep your immune system as high as possible all the time. And
exercise intensely when you're away. Heavy cardio is the best way of eliminating jet lag! Next time you feel weary at the beach,
and its before breakfast, take a sprint down the beach, especially in soft sand which can be particularly exhausting. Afterwards
you'll feel refreshed in a new way. Just push through the heat. The best way to adjust to a new climate is to exercise heavily in
that precise climate. Air conditioning is a fool's way to comfort. If you paid to go to the tropics, don't wuss out with air
conditioning.
