"i started taking latuda on the 20 mg. starter dose and am now up to 40 mg. at night.  i also take 1200 mg. per day of lithium.  i started taking latuda because the lithium was not quite controlling the hypomanic break-through events.  the latuda is amazing.  i started noticing the change about 3 days into it.  the main thing is that i feel calm, the best i have felt in about 20 years.  it does not make me that sleepy, although i used to have trouble falling asleep, and now it is no problem.  it does make me hungry, which i have to fight all day.  i will take hungry over feeling like crap any day."
