Hello all -- After many delays and much research, I am finally starting an abx protocol (cefuroxime and doxycycline for 2 months) prescribed by KDM for a Yersinia infection. I took the first cef a couple hours ago. Very brainfoggy and a bit of dizziness and ataxia. Craving vitamin C. Do y'all think I should start the doxy today, too, or wait a day or two? Is this brain fog going to go away? Update: After 4 hours, a pint of water, 2 grams vit C, some prescrip-assist and orthoobiotic, misc other supps, I feel less like I have been hit by a truck. A truck full of dizzy. Doxy, or no?
