I am a 4 pack plus milk lady, lost 4st12 end of Aug to beginning of December in 2009, losses pretty similar to ss I think. I lost 11lb in my 1st week on both occassions, average loss after first couple of week 3lbs.
I have my extra pack when master T has his tea at 5pm, keeps me going until my soup for my 'tea' at 7.3oish, have still felt light headed on occassions, but that is usually due to the influence of my hormones!
I couldn't trust myself with the portion control needed for the small meal option just yet. x
