<human>: Could you distill the essence of the text into 1-3 sentences?

A little background:

I work for a marketing company in London; which has offices all over the world (Boston, Tokyo, Guyana, Barbados, and Singapore). 

The Singapore office has only been around for a year, and its not doing very well (inexperience from top to bottom). So the company decided to send someone out there with the right skills and experience to go and help lead that team. After a long and thorough interview process with over 10 other candidates, I was chosen as that guy.

I've always wanted to work abroad, somewhere far and different (and preferably hot). So when this opportunity arose, I jumped at it without thinking twice! Luckily, I have no tie-downs like a gf, or mortgage; I can leave my flat at short notice without any hassle.  

As it stands, the logistics of the move are still being planned and executed, on-the-fly. However, I have been told that the company will take care of things like flights, visas, accommodation for the first two months and medical insurance. Again, the details of this package are still being worked out. My current salary is approx £26,000 pa, which translates to roughly S$50,000. The company said they will look at how much they will need to increase this figure; apparently its a **very** expensive city. 

Reddit, I've never asked you for anything before, but now I need to ask you for your expert, worldly, informed (and often hilarious) advice. 

Can anyone tell me what kind of salary I would need to live comfortably out there ? Also, I like to have the 'occasional puff', if you know what I mean. Will I still be able to have this small luxury there? 

Any advice you guys might would be truly invaluable to me.
<bot>: I'm young, unprepared, and about to move from London to Singapore; is there anything I should know before I go?
