"to all starting out on celexa, please don&#039;t judge it by the first 3 weeks.  i am now at 8 weeks and i&#039;ve never felt better.  my doctor said the full effect will be felt at 8 weeks - i can truly tell. the first 3 weeks i was beyond tired, getting up and getting to work was painful.  i&#039;m usually a night owl but i was ready to crash after dinner every night. by week 4 all of my energy came back.  my moods were amazing, my social skills did a 180 degree turn. this medication truly changed my life.  i haven&#039;t tried anything before for my anxiety/depression as i am in my early 20&#039;s. i knew i needed help when my illness began to destroy my personal relationships.  the constant yawing, tiredness, fogginess will go away. your body will adapt."
