Thanks a lot for the responses, everyone. They're all appreciated. I went to family doctor today, and told him about my suspicion of the mercury; but he said he thought it was unlikely. Although he didn't dismiss it completely, he highly doubted it. I'll be doing a blood check and urine check tomorrow to see if anything is abnormal (I have a fear of needles though, haha)

I'm still a newbie to this forum, so I'm unfamiliar with several of these acronyms you guys have been using; but I'll pick it up eventually. I have some concerns holding me back from having the removal done.
1. Ineffectiveness.
2. Potentially feel even worse.
3. Money (although I know this shouldn't be a priority when it comes to health, it definitely matters to some extent). I imagine it won't be too heavy of a burden since it's only two fillings.

I'm worried about the possibility that removal might aggravate my condition. I have read several stories about this happening. If I do the removal, what should I prepare for? How to prepare for it? and how long would it take? I'm currently a very busy student aiming for top universities and I can't really take the chance of getting sick at this time. Maybe in the summer...
