"i  have been taking invega for 3 yrs.  i just increased from 6 to 9 mg. i take it in the morning as part of a bipolar drug medicine therapy.  i still take prozac and lithium as well.  i  didn&#039;t have any side effects starting invega.  my moods are 99% controlled. i&#039;m still bipolar and have very infrequent mood swings but they are not as long or as severe. i did gain 20 lbs. my quality of life has greatly improved."
