For Psychosis "I was put on Fanapt for my bipolar a little over a year ago. I also take other medicines, but this one really did the trick for me and got me on track. I do struggle with the drowsiness and take it early in the evening in order to get up the next morning, but it is worth it to me."

For Psychosis "I've been on this for a month. The symptoms I was put on this medicine to control are under control. It's worked great for that. The problem lies with the side effects. I'm sleepy constantly. I went from sleeping less than 4 hours a night to sleeping more than 12 hours a day. I'm exhausted. I've put on weight, and I have a stuffy nose, head cold symptoms all the time. If I miss a dose, the cold-like symptoms let up, but when I take the next dose, it's back in full force. I have been 'sick' for the last month. No medicine that I've been put on for the 'cold/allergies' helps. It has to be the Fanapt causing it. I'm miserable. I stopped taking it 2 days ago, and the cold just magically went away. Imagine that!"

For Psychosis "I was put on this a few days ago. It does seem to level out my mood, and it seems to make me 'spin out' a lot less. Sleeping better after stressful situations, and am bouncing back from emotional setbacks much better. Only problem so far is I am unable to ejaculate. Hoping they find something that will allow me a sex life, though. I am dizzy and groggy on it too. But I will definitely use this if no other treatment gives me the peace that Fanapt does."
