I've been without for 4 days. I cannot stand my self anymore. I NEED something NOW. Brain zaps and dizziness like crazy I cannot function. Even tho I can't see my lips. They are so numb they feel blue. I cannot stop crying. Been crying 2 days non stop! Today is my birthday I cannot enjoy because I cannot function. Is there anything close to venlafaxin that I can take immediately to temporarily stop this feeling?
