anxiety
"Been on effexor xr for approximately 12 years! I regret taking it. Am on 225mg per day, doctor wants me to taper down to 150 per day! It's a damn nightmare I'm on day 2 of being on 150 mg and the withdrawal symptoms are horrible. I feel dizzy nauseous feels like my head is hot feel very tense, very moody, and  short fuse. I could go on."
