1) years before i had been on accutane for a few months low dose and the months before accutane i was on a few different Antibiotics for my skin.
2) No but a few weeks before my stomach problems began i had my Amalgam filling taken out, they used a "dock" and i made it clear to the doc that i wanted her to be very careful to not leak any mercury, they gave me a oxygen mask to prevent inhalation of the dust as well.
3) I had swine flu vaccine when there was an outbreak in 2009.
4) For about 2 years from when i was 13-15 i was on nexium for acid reflux. I got myself off it by using an herbal formula to balance my stomach (Gi-revive, its mainly DGL and Aloe).
As a side note - the summer before september when i got sick was amazing, i was training hard in boxing, feeling 110% my body was very well adapted to stress.
