Feel like fainting

[Guest guest]

Does anybody sometimes experience like they want to faint, but don't.

I sometimes, especially earlier before starting chelating felt like I wanted

to faint, but don't.

These days much better, but still occasionally feel a bit weak and wanting

to faint for a moment (not the normal lightheaded feeling when standing up

quickly). Then sometimes a bit tired with fast heartbeat and high blood

pressure for few hours and then disappears for days or weeks.

Not brain or heart - had scans done and all is clean.

Has anybody experienced this?

Regards
