Hi Josie, Well done on your weight loss so far!
I'm another midwife, and agree with the others. Plan your shifts, plan your syns and dont let yourself be tempted by the sweets, chocolates, crisps, cakes, savouries, toast... the list is endless as the supply!!. The simple key is that if you dont have one you wont have any (even if you think about it 50 times). I take my own sweets or scan bran cakes then i feel like ive got something nice to have. Don't get me wrong, there are far too many times where I give into temptation so the next big thing is a food diary or syn log. As a health professional you'll be familiar with the saying "If it's not written down, it didn't happen" Log everything, syn everything, plan everything. Eventually it will all settle into a nice pattern of not needing to think too hard about food.
I managed to lose just shy of 5 stone but had a (pretty big) wobble over the past 18 months and am now working my way back there.
Good luck xx
