Thank you all for your inputs! I wonder if there is a relationship between not eating breakfast and having a coffee spike? I don't eat breakfast, I just have my coffee in the morning. I have played around with skipping coffee- I don't spike, black coffee and coffee with full fat milk -both of which spike me. This suggests that it is the coffee and not dawn phenomenon. Cutting out the caffeine isn't ideal too, as I pretty much need it to function! I also don't have a strict morning routine (I work in a very chill place) so can't include it in my basal rate. I wonder though- I do use a pod machine. I suppose it is possible they could be adding something else to the pods.
