All ways thirsty and feel dehydrated

What sort of bgl are you seeing.? How were they when you started? When do you test? These things will give us an idea of what’s going on.
Your food intake sounds low. There are no fats there that you need for energy in lieu of carbs. . Have you checked what the oats do to your bgl?
Do you make sure you have plenty of magnesium and potassium rich foods (or supplements)? Going low carb can mess up electrolytes a bit and it’s not just sodium we need.

 

Low-fat options tend to have hidden sugars. As someone else says - oats might also affect you.
What is your glucose checking telling you?

 

Cut the carbs (like the oats), and up the fats. There's only 3 macro nutrients and you're eliminating the wrong one, fats are fine! You have to have something to run on, after all. No need to go hungry. https://www.diabetes.co.uk/forum/blog-entry/the-nutritional-thingy.2330/ might help you some. And do test around your meals. Before you start and 2 hours after the first bite. You're aiming for a rise of no more than 2.0 mmol/l or less. It'll let you know what agrees with you, and what doesn't. Right now, I'd say, add in some eggs, full fat greek yoghurt, full fat cheeses , more meat/poultry/fish etc, to bulk up your meals. You're starving yourself of vital nutrients, you must be feeling exhausted...

You be good to yourself eh!

if you are diabetic you can cope with fat, but not carbs - I really would advise a rethink on how you are feeding yourself.

 

Bacon and eggs, omelette with left over vegetables from the night before and some cheese.
Full fat yogurt with some seeds and berries.

 

I've brought some low carb wraps from Ocado recently, really nice and 4g carb each so a lot less than normal wraps. Quite expensive though. There is a low carb bread as well which is nice but really small! Omelettes are good, I have them a lot for lunch, chicken caesar salad, soups (use low carb veggies)

 

But your breakfast is a bit of a disaster, you know - solid starch with a sugary liquid poured on top - it would be far better to start the day with a proper meal (excuse my being straight with you, but it really could make a difference to the rest of your life)
I eat foods from the previous days dinner, or eggs and a stir fry - Lidl have some frozen mixes which are really low carb and very convenient. After that I don't even need lunch.
