anxiety
"I too have been experiencing dramatic weight loss with buspar. Just read the last comment and pretty much spot on. I don't get hungry anymore. I'm a 5'7" female who weighed 175lbs. and now I'm down to 120lbs. After two   months of this medicine. Also I noticed I seem to be having some severe OCD thoughts while taking this medicine. In the beginning it was all smooth sailing and now it seems like it's not working. Going to try another medicine."
