Morning all.
Just working through today's posts in order, so forgive me if anything has already been answered!
@northernknickers @PrimaDonna123 @GreeboIsMySpiritAnimal really sorry, I can't help with the technical issues; I rarely use my phone for MN as I find it too clunky so always use my laptop. Hopefully someone else can help you!
@Nonononon here's a link to the spreadsheet It's in the OP of this post - I always post it at the beginning of each week's thread. Sorry to hear you're not feeling great but, as you say, a sore throat really won't be from low carbing 
@rosesandsunflowers
Well done everyone on the first day. I found it surprisingly ok. Had a bit of a headache early evening but I think I hadn't eaten enough. I had a couple of spoonfuls of some full fat yoghurt which helped.
Sorry you're feeling a bit rough - did you read the piece I posted about carb/keto flu? It sounds like this is what you're heading for - should only last a few days. In the meantime, especially with the amount of water you will be drinking, it's really important to keep your sodium intake up. Which means salt - cook with it, add it to your food, and try a hot drink made from either Oxo, Bovril or Marmite.
You also need magnesium and potassium, and good sources of these are full fat natural yoghurt, salmon, avocado and spinach.
B: eggs and bacon (is it better to have fried or scrambled or poached?
Either are perfect low carb, but scrambled will be better, on balance, because you'll get more fat, as you will be making them with butter. (You will, won't you?
)
Sorry about illnesses and trips to A&E - hope that's all resolved now?
@RozHuntleysStump @TheHoundsofLove you do get used to drinking lots of water, I promise you!
@Twit
Breakfast- egg
Dinner- tuna and mayo plus salad leaves
Tea-chicken legs, courgette and spinach
I realise this is just jotting notes down, without the full details, but please make sure you're getting plenty of fat in those meals
@venusandmars that's a great post - thank you very much. And it's so true. M&S are getting better and better at providing low carb-suitable foods (whether intentionally or not!) 
@SittingontheSidelines looks like you have the same problem as others upthread - I'm sorry but I don't know how to correct that for you. The only thing I'd try (statement of the bleedin' obvious really!) would be to delete the app and then download it again? No idea if that will work!
