Thanks Mosaic for the links!
I didn't realise any of that was on here... My whey protein came today so as I've got an early start in the morning then working 8 days straight, I'm going to try a shake and toast until I can read through all the information on here properly, then start experimenting with some other breakfast ideas.
I've read through the first link and its make a lot more sense why the oats are not enough on their own.
Thank you so much for the advice - Lisa
