A month ago I inquired with a nearby hospital on the b12 test. It costs 290usd converted from Philippine peso. I don't know why it's so expensive here maybe it is not common among the tests hospitals use here. I probably cannot afford that for a single test, the vit d test i can.

That was my earlier guess after all of the research i've done. i am low on b12 that was why my doctor could not get the iron levels that she wanted. Made me more eager to start the regimen asap. Right now i am not taking any acid blocking drugs. But i think i will have to soon. Hyperacidity attacks more often now. I am thinking that is where i get the nausea, from my hyperacidity attacks. I only get nauseous while travelling and when i feel the acid has finally digested, the nausea is gone. But i am also a bit worried that it may be TIAs. I would have to observe my body more.
