Unfortunately you have to work out for yourself how many carbs you can comfortably eat - there's no "one size fits all" as it depends on, for example,
(a) how our individual bodies can cope with handling carbs
(b) whether we need to to lower our glucose levels, reduce our weight, or both
There is information on recommended blood sugar levels
here, which you can use as guidelines and, if you wish, to set your own (realistic) targets. Using your meter before and after meals will tell you how you are doing in relation to these figures, and you can then adjust your diet and carbs accordingly.
But whatever, you have to decide on a carb level which (still) allows you to eat a healthy diet, and that you will be able to keep to in the long term if necessary, as it may not just be a quick fix but end up being a new lifestyle, as CollieBoy has so charmingly explained it!
