I can understand your frustration about the unfairness of meds taking away the highs but not the depressions, when what you really want is to experience the highs if you already have to take the lows. I often crave hypo/mania. I just can't help it. Even though I know that every manic episode does physical damage to the brain and worsens the prognosis for the illness in the long run. So really, it's technically a good thing that the invega is keeping away the mania for the sake of your brain's health, but depression is damaging too, so it's kind of unavoidable.
