Hi Jim,
Welcome to the forum! 🙂
When I was newly diagnosed, my nurse asked me to keep a record of my blood sugar levels before and 2 hours after a meal (breakfast, lunch and dinner). She asked me to do wait 2 hours afterwards to ensure my record was accurate but I think this might be more of an individual care plan thing! I found that to be so helpful. I notice that lunch is a particularly difficult meal for me and I usually end up with high glucose levels afterwards!
I was referred for an education group (it was online via zoom) with a dietician etc and that was helpful in learning about what foods were most helpful for me. I would recommend speaking to your diabetes nurse to see if they can refer you for this.
There are lots of advice and support on the forums - look after yourself! 🙂
