I get that too with my low blood sugar, like you do Carol. I carry sugary sweets with me. Lol
Hazzell, I don't know if that is your problem, have you had your blood sugar checked? You also had a brain injury, so that could do weird things to your body too. You could lower your dosage back to 1.5 mg of LDN for a while and see how you feel.
I hope you feel better soon. It is so hard to tell what is caused by what. Meds or diseases.
