Apparently I forgot to take my Effexor last night. I could remember to take the horse-pill vitamin, no problem, but not the Effexor. I realized this when I got up and the world kept rotating to the right. And when it took me two tries to get out of a straight-back chair because I was so dizzy. So I took my pill and now I get to wait while it gradually, gradually begins to take effect over the next 3 hours. I hope to god I don't ever have to stop taking this for good, because I don't look forward to withdrawal.
