"this medication was extremely effective at stabilizing my moods.  the problems that i had made it so that i could not continue on it and therefore needed to rate it so low (because of the severe side effects).  first off, i literally  saw double for several hours after taking it.  do you remember the wrigley&#039;s double mint gum commercials?  well literally that&#039;s what i experienced.  it did go away after several hours afterward but was really weird and gave me a headache when it happened every morning.  my skin, especially my lips, would get numb and tingly.  the biggest problem though was that it gave me constipation so bad that nothing i ate or took could alleviate it.  the only way i could ever go is if i took a heavy (not mild) laxative."
