Citalopram
"To all starting out on Celexa, please don't judge it by the first 3 weeks.  I am now at 8 weeks and I'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'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't tried anything before for my anxiety/depression as I am in my early 20'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."
