Hi, Gigi! You could try taking it as directed because the side effects resolve within a few days to a week or so. By stopping the medication or missing/skipping doses you're risking discontinuation syndrome with the symptoms you describe.
The only safe and effective way to wean off antidepressants is by using a decreasing dose schedule supplied by the doctor who prescribed it for you.
The half life of Effexor XR is about 15 - 20 hours so it will take about 3 - 4 days to completely leave your system, although you may continue to feel discontinuation symptoms for several more days.
Best regards, Wildcat
