I agree with you here. Cravings are a subjective thing - they're not like breaking out in spots where either the spots are there or they're not. There are emotional and psychological aspects to them and it's hard (at least for me) to separate the two.

Is it unrealistic of me to hope for a home blood insulin meter so I can figure this out once and for all, or would that just be more confusing data? I would donate a crap ton of money to crowd fund this. I want to know if certain things I'm consuming are causing an insulin response but I've conditioned myself to ignore hunger/cravings, or not. Perhaps an anti-hunger affect is taking place that's more profound - example, coffee. The Splenda could be causing an insulin release, but the "fullness" factor of the coffee counteracts it for me. I'd like to know.
