So what are the essentials you need when you're facing times like these during your vacation?
1) Water
Drink a lot of water. It doesn't matter if it's plain water or juices or sports drink, as long as it's fluid. But if you have throat irritation or cough, I suggest you not to drink anything citrus-y. Take a lot of fluid to lower down your body temperature. This is the most important part.
2) Light Food
You might want to forget about buffets and such. If you don't feel well, you might want to eat something light like bread for example. Something to give you energy (to walk at least... ).
3) Meds
If you can get paracetamol, this could help with relieving headaches and also fever. If you can, try not to take meds. But, in my case, I need it really bad. Especially flu meds.
4) Sleep and Rest
Regardless of what you do, where you are, if you're sick, get a lot of rest. This will help a lot with recovering. So if you want to get on your feet the next day, then PLEASE, take a good long rest.
I guess, that's all I can think of now. I'm still sick but I'm doing this (not good). Until then people.
