Hi gezza, welcome.
Have a look through the diaries, they are great for tips. I'd say drink lots of water and take 1 day at a time. Days 2 and 3 are tough but keep at it.
I haven't tried all the meals and shakes yet but I like most of the bars and meals I've tried. I really don't like the soups but everyone is different
Have you done a vlcd before?
