Hello and welcome. Your readings seem absolutely within normal to me. I would advise that you see your GP,
taking your readings with you.
Test before the first bite of a meal then two hours after first bite. Record what was in your meal and the readings. The more readings/data the more info these provide for your GP.
If you could, let us know what a typical day's menu looks like, we may be able to help you to tweak your diet to improve the way you are feeling. Best wishes.
