My sim has had this ailment for what seems like ever and nothing is working, based on the comments here that I've skimmed through and read, EA should create in the next patch a way for us to turn that feature off if we don't want it attaching like a leach. Every time she comes home from work or an even she runs to a toilet and throws up, she's covered in an orange and yellow rash which has now changed to paint because she is an artist by trade. it's quite annoying, the mood swings? I'm in perimenopause and even I don't have THAT many shifts in mood.
