wow, thanks for all the replies, so many great ideas, ive gone from having no ideas to having too many to choose from lol

! i love the home spa idea, im definatly doing that one, i actually trained as a beautician so thats no problem for me, my local chemist sells individual face masks for £1 and little pedicure kits for £3.
my ex gave me an amazon kindle for xmas but ive only been downloading the free books so maybe i will get one of the more expensive ones for one of my goals. and i love the saving up for a bigger goal idea too! and the necklace/ tealights idea is very cool.
the rewards will go a long way to keeping me motivated, i want the reward more than i want the chocolate... crisps... whatever im craving at the time. of course health and weight loss itself are the main reward, but i dont often treat myself and having something nice when i achieve a goal will be a good little motivator to keep going.
