I think I might have Attention Deficit Disorder. I have been reading about how the mercury in immunization shots can cause autism. The last shots I had was the series for hepatitis vaccine in 2001, flu shot in 2001, and flu shots in 2005 and 2006. Since 2001 I have been having symptoms of ADD like trouble concentrating, making careless mistakes at work, job hopping, and have problems with forgetfulness. I am 32 years old.
