I've been here long enough to know what to bring around the city or pack for quick country tour. These products I literally could not live without.
#1 Tiger Balm
Tiger Balm is a miracle worker on sore muscles as well as bites. Ask your masseuse to lather some on before your yogic Thai-massage and you will be in heaven (or should i say Nirvana?).
Other uses include: rubbing on your temples for a quick pick me up, rubbing on your neck/shoulders when sitting at your computer for 24 hours takes its toll, or rubbing anywhere on your body at any time for mentholy warming, burning, cooling tingling magic. I like it on the inside of my forearm, near your elbows. (Thanks Emily) Weird, but totally sensational. As you can tell, it's never far out of my reach and I use it generously :)
#2 Prickly Heat, Lavender or BabiMild, purple
February through May, this will safe your life. When you're hot and sweaty, (which is all the time, even after you shower) pour this old-lady powder all over yourself and your sweat will tingle away. Its absolutely magical, and will leave you feeling indescribably prickly and fresh.
just do it. you will smell better too!
#3 All-purpose Sarong.
Forget your towel? Your $3 hostel doesn't have sheets? Want to wear a skirt? Do you have to shower in public? Do you need a blanket on the bus? A pillow? Need a handkerchief to cry into when you miss your bus? Need somewhere to wipe the gallons of sweat constantly dripping off your face, or the leftover mango all over your hands?
USE YOUR SARONG.
I think 75% of my facebook pictures feature this Om-ed Yellow-Wonder. I. Love. It.
(It should be noted that I also used it as a tapestry/window insulator when I was living in Chicago.
