What is the best med or supplement for and overactive sympathetic nervous system that doesn't sedate you? Thanks Docs!
???: There is such a condition as sympathetic hyperfunction syndrome, which has various manifestations; but the phrase "overactive sympathetic nervous system" is far too vague and imprecise to refer to any valid physiological concept.

Neurotransmitters: This is a very complex question, and you need to discuss this in detail with your treating physicians. Both Norepinephrine and serotonin act on the dorsal horns of the spinal cord to inhibit excessive transmission of nerve cell fibers, thereby decreasing the central (brain) perception of pain. Nortriptyline should not worsen that, and may help some. The SNRI's medications help with pain relief. ...Read moreSee 1 more doctor answer

I assume you have had endocrinology testing to rule out hyperthyroidism, pheochromocytoma, etc. If so, perhaps a stress management program would effectively treat your symptoms best and you have been recommended to avoid alcohol, caffeine and nicotine. Your physician would know best whether beta blockers would help. ...Read more
