I hope you are still here because I might have the solution for you. It sounds as if you're a carbohydrate addict (CA). There is a test for it on a ticky at the top of the CAD/CALP forum here. If you are then CAD/CALP is the WOL for you, it will solve your insulin problem and control your insulin/appetite. There's a thread there called CAD/CALP overview that explains it.

Know that it's not you but rather that you have a faulty insulin regulator and that putting carbohydrates in your mouth more than once a day be they cake or veggies will set you off. No wonder there didn't seem to be any rhyme or reason to it!!!

I hope you give CAD a try. You are under so much stress otherwise that it would be great if you could be relieved of this one. Good Luck!!!
