Thanks for your reply. Just something high carb or sweet or both, I guess. I haven't eaten anything high carb or sweet since the beginning of September. No desserts, no nothing. No bread, no fake bread. I guess during that time I've had half a dozen squares of 90% chocolate over the period but the last of those was a week ago and they're not exactly sweet! I'm sure I have had problems with sugar in the past - not sure if it is addiction because obviously someone who is undiagnosed as T2 (as I think I may have been in much of my adult life and long long before I became overweight) has a funny relationship with sugar/carbs. I don't drink alcohol by the way, so that's not the cause.
You know, I used to love making bread. Especially cholla and pain de campagne. I think I've avoided keto bread for fear of starting all that up again.
