I was on Effexor for over a year. Three weeks ago I decided that I was finally going to get off the medication and went through hell with the withdrawls. The only lingering symptom is the night time panic attacks and anxiety. Feels like I'm up every night with this. If I can actually sleep then my daughter is awake which causes my husband to complain and triggers another panic attack which is where I'm at tonight. I would not wish this feeling on anybody.
