I'm sorry this has happened to you but you are not alone. My Dysautonomia symptoms started with migraines, flushing, food & environmental allergies, & I couldn't sweat. Later I changed to flushing & sweating, seizures, exhaustion,shaking, insomnia,IBS, & the list goes on. I reacted to every medication I was given until a neurologist gave me Neurontin. That helped migraine pain & I could sleep, it also helped with the flushing & anxiety. It wasn't a cure but just getting a nights rest helps me cope with things better. I've had Dysautonomia for approx 25 years & Neurontin/Gabapentin & Ativan are still the only meds my body will tolerate. Hope you get help soon.
