all i can give you is my heartfelt sympathy, and maybe the encouragement that comes from knowing that i experienced a lot of your exact same symptoms!!! the way i got through it was to keep reminding myself that the worse i felt, the more detoxing my body was doing... also, for some reason, i would continually get an extra boost of confidence every time i used a ketostix to monitor my ketosis. i know they are mostly unnecessary, but every time they came up purple, i got a rush of accomplishment :)
