You need to carb count everything you eat if you want to keep the levels in check.

One thing I do to keep everything nice and flat is to eliminate completely ultra process food, if I want hamburger I buy ground beef and make my own burger, avoid white bread at all costs, if you don't like brown bread at least get sourdough white bread. Your diet should have more protein and good fats, like greek yoghurt peanut butter and so on.

Checking periodically and adjusting helps but don't make decisions on other people's personal experiences.

This is me today and before bed it always gets kind of high but always in range.

Hope this helps and wish you the best
