C.flem, as a general rule of thumb, "low carb" is 130gr or lower, but other than that, bearing in mind you have, and of course have to have, insulin to help you manage your blood glucose scores, you can make it up as you go along.
Some who low carb have limits on how many grammes they will consume a day, or there are others, like me, who take a bit more flexibility, as long as my blood glucose numbers stay in my personal range.
Big caveat here now: Provided you are confident carb counting and adjusting your insulin doses, in your shoes, I might experiment a bit. If you are not confident in carb counting or adjusting your insulin, it might not be such a hot idea, as your insulin needs are likely to change, and depending on how low carb you go, they could change a lot. In your early days you will need to be testing a lot, or if you are a Libre user, scanning fairly frequently.
Often those who go low carb find they drop a pile of weight straight away; some of which is water that has been retained in the carbs they have been previously consuming.
Initially, I (again personally) would try to do something consistent for the first couple of weeks.
I haven't eaten bread for over 6 years, but that was a personal choice. It just didn't seem with it to me, but others do have modest quantities of bread, and there are also some (relatively) lower carbs out there.
