"i was surprised to feel lightly speedy my first dose as i heard the serotonin has to accumulate in the body. i had a major head injury in july 1998. i have memory and attention to details problem. intellectually i&#039;m fine. i notice my attention to detail has changed for the better. naturally the memory problem caused by damage to the hippocampus is still there and might be somewhat ameliorated, but i am having that tested later this month to compare my score with older testing. otherwise my impression might be subjective reflecting wishful thinking. i like this medication and hope it stays effective."
