I second Jen29 here, Gingerkat. Take it from one who knows: suddenly going off your meds can make things much, much worse.
But I'm not here to judge, and I understand the urge. At least make sure that you aren't on any meds that sudden withdrawal from which will make you sick, like Effexor (does this sentence make sense? You get the gist).
And don't be too proud to go back on them AT ONCE if you get too down or 'out there.' I can't tell you how many times I've slunk back to my meds with my tail between my legs after having my *** kicked by a tidal wave of unmedicated depression.
