I've been on it off and on--mostly on--for 3 years now. In part at least it's been a godsend. I had the weird experience of worse side effects on a lower dose. I would get urge incontinence (as soon as you think of peeing, you're going to go before you get your pants down); sleepiness so terrible that I would have to go out to the car at 10AM at work and sleep for an hour; my voice and hands would get shaky; but I didn't feel depressed. My doctor doubled the dose to 160 mg and had me take it all at night, and all the side effects went away. I just worry now about Parkinson's or tardive dyskinesia when I'm 60.
