For a few weeks, yes. After that, no, it's more like I'm exactly the way I was before I went on them, which is discouraging, but not worse.
I am pretty sure the studies that have been done on this show similar things, that is, the meds don't create a dependency except for the period it takes to withdraw, usually a few weeks. (I am talking about SSRI's, for reference.)
The last time I went off them for 6 weeks I was somewhat better than I used to be before I started them. My extreme social awkwardness and obsessiveness was down a lot. Good to know.
