After 8 yrs, I spent 8 months tapering off venlafaxine 150 mg. I was down to 35mg experiencing every side effect and my doctor switched me to Wellbutrin 27 days ago. Went to ER yesterday with severe vertigo & nausea. Can’t work, can only sit. Do not move head or eyes and sleep. Do the withdrawal symptoms get worse over time until my brain cells reboot? Forget about seeing my new doctor, I am going today to a mental health walk in clinic to get expert help. Thank you for your input.
