I have taken venlafaxine 37.5 mg for 3 months to help my anxiety. It worked well until about a month ago. I started getting nauseous, dizzy and headache an hour after taking. My nurse practitioner told me I should go off it. I asked about tapering off and she said to take one every other day for a week and then stop. The morning after my first skipped dose I woke with a weird brushing or swooshing sound in my head when I turned my head. It went away and came back briefly until I went off the V. Then it came back stronger and constant whenever I move. It's getting worse every day along with ringing ears, nausea, dizziness, headache, neck pain and other body pains. Is that sound in my head what people are calling "brain zaps"?
