My meds made me lethargic too. I put on like 60-70lbs as a result (I stopped exercising). I made a deal with my pdoc that I could begin cutting down the dose if I joined a gym. Given that gyms are so expensive, I've yet to do this.

Although, I did recently stop taking my meds (for 5 weeks)... don't know why, exactly. I got my energy back a bit... but then I began getting symptomatic so I figured it best to go back on.

I'd say stick with the meds for now, simply because you've been psychotic recently, but definitely tell your doc that you want a lower dose as soon as is realistically possible because this lethargy, if not taken care of, can lead to physical problems. Like my weight gain, which has wreaked havoc on my blood pressure, etc.

Best of luck. I hope you get this figured out sooner rather than later.
