Hi Drone3, I don't know too much about such things, but is it a possibility that you are going into ketosis and that this is causing your mood swings? It sounds as if your carb intake is very low indeed if you are off both starches and sugars. I can't eat much fruit but have been trying to eat enough fruit in small portions so that I avoid ketosis. Many regard ketosis as a good thing and they weather the transition side effects in order to experience the perceived benefits. I personally prefer to avoid it if possible. Maybe you could Google ketosis, or ketosis flu, and see if the symptoms you are experiencing tie up with that.

Spondyloarthropathy with symptoms of AS, Sjögrens and fibro. Previously took Celebrex, Methotrexate, Trepiline, Prednisone which seemed to trigger a flare and my illness became much worse. Symptoms now kept mostly under control with NSD, as well as cutting sugar, dairy and yeast and food intolerances. Mostly pain free now and all symptoms massively improved.
