I'm about 5' 2.5".

1. what do you weigh now and/or generally what size clothing? (this may be too personal - if so just don't answer)
I think I'm around the 52-53kg mark, but not exactly sure. Fitting into sizes 8-10.

2. what is, in your opinion, your ultimate goal weight? (ie, for me i'd love to weigh 50kg but realise this is unrealistic)

3. what would you be happy/content to weigh (or what size)? (ie your realistic goal weight or size)
My ultimate goal weight is the same as my content weight... around 50kgs. The biggest thing for me, though, is being in good shape... which means getting rid of the flabby bits that I don't have when I'm doing reasonable exercise and eating well. Last time I was there, I was 50kg.

Like Dachlostar, I've been at 45kg before (most of my early 20s, following on from a bout of glandular fever) and I was too skinny. Didn't look healthy.
