Yep - ignore the family - you need to be surrounded by encouragement and nothing else.
I don't have a set time for when I have my shakes - I know that some people try to hold off for as long as possible in the day, but that doesn't work for me. I drink a 500ml bottle of water when I get up and try to drink another before I have my first shake, which is always before midday. I find the longer I leave it the more hungry I feel and then the first one just doesn't fill me up. Once I've had that one, I can go a good few hours and this continues throughout the day. I've just finished my last one, and haven't felt that hungry throughout the day, although it's been a busy one!
And as for the toilet trips - if I've drunk a lot of water, sometimes by the time I get downstairs, I'm back upstairs again! There's definitely no small bladder - in fact, a sign that the diet's working for you!
If I don't get the chance to say it to you before then - all the best for Sunday.
