"i took celexa (citalopram) for about 8yrs. i started at 20mg dose and worked up to 40mg over the yrs. i found i was happier in the summer, and with my doctor&#039;s help would decrease my dose for a bit, but in winter i&#039;d bump it back up again. mood wise, celexa did wonders for me. i was able to live happily for yrs. missing a day or two was hell, between the brain zaps and bouts of crying i was a mess. the downsides: my libido disappeared. completely. gone. i used to have a very healthy sexual appetite. i also gained about 60lbs while taking this pill. i can&#039;t blame it all on the pill, but it didn&#039;t help. overall it was a great mood enhancer, but take it with warning."
