We are all very different. I believe
@Kaz261 is at over 100g a day (correct me if I am wrong, Kaz?) while Nosher doesn't count at all, and I roughly fall in the 20g-50g range, but I only go up to 50g on high days and holidays. lol.
For me, the biggest factor is not the number of grams, but rather what the foods are.
I can eat unlimited amounts of green veg, and foods with fibre, but give me something like Pringles or a slice of toast, and I spike and drop really quickly, even if the carb grams only add up to 20 or so.
It will take some experimentation, but you will quickly learn what constitutes your personal comfort zone.
