what would you do in this situation?

okay. as some of you know ive been in and out of hospitals recently.
they still havent identified whats wrong, theyve identified lots of other things tho, and i got a prescription through the post yesterday for one of them.

the point i think is to poison me so that the thing itself is poisoned.
now the dilemma i have is that they dont actually know whether its causing me any problems or not cause a lot of people have it in their system and its fine...

the side effects i could get though are serious and crazy.

should i take the prescription and suffer the side effects and hope it works?
should i take the prescription and keep an eye out for side effects then stop?
should i not take it?

add into thois the fact that i have a hard enough time taking tablets as it is....

as you can see a dilemma.
