Just wondering if anyone's symptoms are substantially worse at night. Specifically, I notice that at night I get very lightheaded, weak, dizzy...and when I am standing I feel worse. Also accompanied by nausea. Perhaps this is related to my lack of sleep...insomnia most nights. But I truly feel much more sick at night. Also, I get a feeling of heat rising in my body up to my head...break out in a sweat. Does this all sound nuts or can anyone relate?
