migraine prevention
"Works well for both my Migraines with Aura and Postural Orthostatic Tachycardia Syndrome. No side effects.

For POTS, it works well for my overall symptoms, such as the improving my cognitive performance, reduces the fatigue to a some degree, and helps me tolerate exercise longer.

It only reduces the tachycardia itself by like 10BPM, but that is far better than nothing."
