What's a simple, cheap treatment for my vasovagal syncope?

Try this: Vasovagal syncope, which is accompanied by a fall in BP and often slowing hr, always has warnings which consist of nausea, feeling hot, becoming lightheaded, and visual changes such as darkening. At the first sign, lie down. If possible, elevate your legs. There are two benefits: it will raise your BP and avoid injury if you do faint. Other hints: always eat breakfast. Betablockers help.

Squat or make a fist: There are many medications advocated, but few proven to really work. The faint can often be prevented if you do an isometric maneuver, which raises your blood pressure. An example would be folding your arms in front, grasping arms and pull them apart. If circumstances allow, you can also squat down or simply lie down on a couch.
