Hi everyone. New to the board. I have dysautonomia and autoimmune disease. I seem to be very sensitive to meds and supplements. Wondering if normal for most? I have had increased dysautonomia symptoms after taking zithromax, vigamox eye drops and most recently Zinc? I get increased heart rate, sweating, difficulty breathing, shaking chills, dizziness, and brain fog, and sometimes accompanied by stomach symptoms. The zinc dose was very low and flare lasted about 7 days. Anyone else have same problems? Thanks!
