I get very sian when I think about work. 
Certain colleagues can really make you dread
work to a certain extent. However, delving deeper into the
issue, this is the lowest, most bearable level of sian I've ever
experienced in my entire working life put together simply because
all the sian-ness is offset by the astounding number of days off I
get to enjoy! 
Sian-ness can be offset by the following ways :
- Embark on a new hobby, or become fiercely engrossed in a
current one;
- Watch TV / Cable / DVD;
- Go out with friends;
- Eat a lot of your favourite food;
- Drive around;
- Explore new areas of your neighbourhood;
- Erm... engage in lots of boudoir gymnastics 
;
- Shop shop shop!!! (can even shop online without leaving
the house and still in your pj's these days! 
); and
- Laugh at the antics in the forums!
