"started on fluoxetine a month ago, 20mg.  felt very tired the first week and nothing else.  just started taking 40 mg a few days ago.  my wife swears she notices a difference, says she doesn&#039;t feel like she&#039;s walking on egg shells around me anymore.  one thing i&#039;ve noticed is things i used to dwell on, i can now think about them but now put them out of my mind relatively easy.  before the meds i would dwell on things, couldn&#039;t escape the negative thoughts.  things that are out of my control don&#039;t haunt me nearly as much"
