Thanks (once again) Karen for your thoughts/suggestions...
I might well have to give the carob another go... It is an Explorer diamond & my body did seem to crave it (& ghee) about 18 months back
Typical of me, I overdid it at that stage, so couldn't face either again...
Then (possibly while reacting to something else) I got worried, since carob is related to the soy family, & being that I am very allergic to soy, I gave it a miss after that for both reasons??!!
Hmmm... now I am craving carob
Oh & cheers re the suggestion of Vitamin C & B6 - I had started those again & they do seem to be helping... in spite of me running out of quercitin?!
