This.
Horrible, isn't it?
Brushing my teeth makes me want to just throw up, and I can't even look at food until about 12.
I genuinely thought that this was quite rare, I'm the same and have been for years. I've gradually forced myself to eat breakfast every morning and the portion sizes are getting bigger and more fillings.
Previously I'd skip breakfast because I was feeling so physically sick every morning (sometimes vomiting after trying to eat breakfast) and be an unproductive grumpy shite for hours. Then I'd eat very little due to a complete lack of appetite at midday.
Eat whatever you can stomach in the morning to start off with and wean yourself onto healthier foods as your body gets used to breakfast. I still wretch most mornings, but get on with it and feel much better at work for the healthy breakfast.
It's strange though, I only get it this on weekdays. I can wake up on the weekend and demolish a huge breakfast.
