"i took paxil 20mg for 8 years. it is excellent for depression, anxiety and social anxiety. i completely lost all anxiety, shyness and experienced relaxed euphoria. i excelled at work and dealing with people. however it is very sedating, i would drink coffee all day while on it. i look back on those 8 years and it all seems like a blur.  sleep very deeply and a lot but at least i was happy. i&#039;m now in my mid thirties and was recently switched to celexa because i started finding it difficult to achieve orgasm on paxil.  bad decision...i now experience anxiety from the moment i wake up, shortness of breath, agoraphobia, terrible and obsessive thoughts, and racing thoughts and a feeling that i am going crazy. i&#039;m going back on paxil."
