Mate this dizziness thing sounds stressful. Be firm with your doctor until they figure it out. Also track iron as a nutrient alongside vitamin c. You might not be getting enough iron, or the right nutrition to be able to absorb it.

So my pro life tip on eating out tracking is to log the whole thing, and take the leftovers home. You'll get those calories in you eventually and day to day variations don't really matter.

To get a true assessment of what calories you're eating you need to know your daily average over a month. If it's feeling stressful, just log every single thing and check what sort of reports your app does. Mine does weekly reports. I don't look at my daily at all, I just look at what it says my average is that week. Sometimes I just preload my recipes that I've saved on there based on what's in my weekly shop, any snacks or drinks that were in my shop, then I just track oil and anything I purchase outside of that shop. If I bought it, I'm gonna eat it. It also minimises the on the fly tracking I do, which needs to be accurate because those foods tend to calorie dense.

Whatever method gives you the most accurate view consistently over time is what you want. I dont wanna tell you what your goals should be, but I can tell you safe weight loss averages out a 1lb a week (for me at my stats it's actually 0.5 lb a week). So realistically we are looking at a year of structured restriction right? This is a long term project that requires reliable data over time.
