A rundown of some of the stuff people don't tell you when you move to London and how you can make it through those first few weeks!
After work drinks
Nobody in the history of ever has said 'fancy a drink?' and actually meant one drink, fact. After work drinks happen in London Monday-Friday and you basically will get totally hammered. How do you survive this without bailing on the social events? SNACKS. Get yourself an 'after-work-drinks-snack-stash' to keep you going.
The UK so has the tube system wrong compared to the spacious, air conditioned glory that is in Spain and alike. There are a few things you need to survive, no matter how many stops. First up, music. Load your iPod or spottily account with as many tunes as poss. Also, you need reading material (always grab the free papers). This combo means no awkward eyeballing with the tube weirdos.
Oyster card, obvs. You don't want to be messing around with tickets. Also, you need a cute oyster card holder, I got mine from paperchase.
On top all of this you need a good deodorant because it gets real sweaty on there. I would massively recommend Sure Maximum Protection which is a bit pricier than others, but works way better.
As well as permanently drinking, everyone likes eating too. This can get pretty costly though, so make like some of the people where I work and have Friday as your lunchtime treat day and try to take your own food in or hit the supermarket on all the other days.
Always have your phone charger or a portable one with you and make sure you keep it well charged. You don't want to get stuck somewhere on your own after the after work drinks with a dead phone.
I'm sure there is more, but hopefully some fellow new Londoners can relate!
