These effects occurred mainly via the β(2)-adrenergic receptor.
Regarding NAD+, this is just an indirect effect
I took low doses of norepinephrine occasionally for some time since I also had allergies with breathing issues. The half dose was sufficient for an effect like others might experience when taking meth, which basically is a large dose of the same medication dissolved from the antihistamine and then sold as a drug. The effect was so severe, I couldn't sleep, my heart was racing, strong heartbeats, hyperactive, euphoria, intense thirst. And the wear-off was the same as well, which means I was completely ruined afterward. Very small doses might be more helpful, but it's impossible to get prescribed separately due to the meth issue. They even took the combo with the third-generation antihistamine off the market here.
Many drugs targeting dopamine have been use with some improvement in fibro, restless legs and ME/CFS , even though they are not approved for our diseases.Dear PR-members
If I understood this the right way, Dr. Ronald Davis' latest research points towards NAD+, tryptophan and dopamine. Did anyone have any success with some supplement and FDA approved drugs which targets those things?
