I take this but for my delusions. I don't get anxious if I miss a dose but it could be because it's targeting your anxiety. When my gf misses one of her anxiety pills she always feels more anxious. She said her doctor told her it's because the level of the drug in her system isn't consistent and as the levels lower her anxiety rises. She's not on risperidone but I would imagine it could probably be along the same lines.
