hey jinx, i think it's quite unlikely that you have a permanent brain damage. I am not saying your brain is not poisoned.
Even people with lesions can recover well. The MRI will probably be negative and then the "It's all in your Head, take some pills" crap will start again. <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />

It's good that you do the MRI so you know what is going on. Good luck...
