I had the same problem with Invega so if risperdal did it to you Invega might too. I just never told anyone about it because I can't stomach the thought of stopping Invega. It's the only thing that has tamed my manic and mixed episodes. I haven't been full blow manic in over a year. I have had a psychotic episode since starting it in July of 2014. I already have a child, plus my husband died and who knows if I'll ever find anyone else, so I'm cool with not being able to have any more kids. But if you want kids then yeah you may have to get off. Good luck I hope you can find an alternative.
