Oh Skinnier Me...sorry you're struggling!
Usually hit Ketosis about Day 3/4. Which is when the real 'hunger' subsides.
I actually bought some Ketostix from the chemist, just so I could confirm it - makes me feel better some how, knowing I am actually burning fat now.
Have you tried splitting your shakes if you like lots of little meals and are you drinking plenty of water?
I don't often find I'm hungry but I find I want food!!
I kinda like that though, as it makes me realise how much I must eat for no reason - bored, tired, time of day, just cos I thought about it etc
I found LT really good for that 'educational' value last year.
Keep at it hun - the first wk is meant to be one of the hardest and you're almost there. Just think how good it'll feel at your weigh in when you've had a big loss x x
