My husband is on this for bipolar disorder and I don't know if it's the medication working or the fact that I was about to leave him that made him act more stable...but either way, he's doing a lot better. He's also on paxil for depression. His job requires a lot of physical work and strain, so when he's at home in the evening relaxing or laying down-he's out! In other words, it can make you feel tired and lathargic. I was on this medication before too and it not only made me tired, but I was hungry all the time...not starving, but I just wanted to eat all the time. My advice: get checked regularly because this drug is hard on your liver...or is it your kidneys? One of those:) and exercise because you'll need the energy boost that working out gives a person. Hope this helps.
