If you're on holiday somewhere in Greece or the Greek Isles this summer, chances are you'll be mauled by mossies.
Get to a pharmacy - avoid all the expensive stuff they've laid out in-store and ask for Fenistil Gel from behind the counter. It comes in a tube in an orange box and costs around 3 euros max. This gel acts as an anti-histamine and helps with the healing process. Also managed to find that you don't get too itchy and scratchy too which is a bonus.
