hun dont quote me on this but i think you have 1/2 a stone before you can change your target..yes it is harder to maintain as there are no rules to follow as such, i had this disscussion in my class a couple of weeks ago as there was a lady in the same situation as you..out come try and eat more healthy bs, a few more syns,but like you said you dont want to blow all your hard work..ive been at target for 4 years and still find it hard 2 stay bang on target im always losing,then putting on again,it does does do my head in sometimes!!xx
