Treehouse, wellbutrin acts more quickly than many ADs (at least the SSRIs, which can take weeks). You will probably feel its effects within days (depending on the dose). I'm not saying you will feel better within days (although maybe you will!), but you will probably feel effects that soon, which may be uncomfortable. Some people have a hard time "coming on" to Wellbutrin because it can be anxiety-provoking. The first few days may be hard, but this doesn't mean that the next few days will be equally hard. So if you want to give it a fair trial, power on through any initial discomfort. If you just can't handle it, or your anxiety goes sky high and is unmanageable, report in to your doc. Because wellbutrin can be hard to come on to, many docs do not give a therapeutic dose to start. Although I agree very much with farmergirl, that "wellbutrin is a good med," I have known several people who could not get through the first few days and so they never had a chance to reach the sweet spot.

Good luck with this! There is no harm trying a new approach.
