@Nayshiftin - Patti and I personally only know exactly how our Type 1 bodies react to chocolate. However you know how elderly folk used to say to you that a little bit of what you fancy does you good? Well buggrit, afraid both of us would by now both qualify as 'elderly' at least to the casual observer though both our personas would categorically deny that - but sometimes you really do have to try things before ruling them out!
My main caveat about such things is, if I'm going to be naughty, it has to be worthwhile so I allow myself to cheat sometimes, yes, BUT only with things I really really like! (It's also possible that actually being able to stop at that 'little bit' plays a part. My parents didn't have 'more than enough' disposable income when we were little and hence I spose we gradually learned how to savour any special treats properly, rather than just expecting them to be available. Cos they weren't!)
