No worries man...
Here's a few tips for everyday mozzie protection... as I said before, cover up skin from dusk through til dawn, as the biters are nighttime predators mostly. Cover any other areas of skin with DEET - if you haven't got it already I would buy it in Thailand, as it's likely to be cheaper. I always go to the nearest Boots Chemist in Bangkok and pick up a silver bottle of tropical-strength DEET-based mozzie lotion. (There's a couple of Boots on the Khao San Road if you're staying there, otherwise they are in the main areas like Sukhumvit/near Paragon/Siam Square).
If you get time though, visit Boots in the UK and try to pick up one of these - they cost just over a fiver:
The idea is when you get a bite and it starts to itch, you zap the skin around the bite with this thing, which delivers a tiny, tiny electric shock. It apparently deadens the nerves around the bite, stopping the itching. I swear it works... I don't think it's a placebo, anyway!
As a result your bites will heal faster as you won't be scratching them (which deadens the nerves also) and potentially making them bleed and even scar.
Get one before you leave... you'll find others borrowing it off you as soon as you tell em what it is!
