Sorry to hear you are getting these side effects. When I took effexor I had similar side effects and they did pass. It took a week or two from memory (It was years ago). This drug is known for its side effects but also for its effectiveness as an antidepressant. I hope it works for you. I am now on Pristiq, a newer version of effexor. It doesn't have as many side effects for me. In fact none after the first few days.
