I have been on effexor for years. I haven\\\'t had any weight gain, on the contrary, it kills my appetite, but I cannot wean myself off it. I get a racing heart, and feel like I am having a heart atack, heart palpatations, pounding heart,pounding in my ears,and hearing loss. I also experience body tremors and convulsion-like body jerks. I also get the \\\"brain shivers\\\" but entire BODY SHIVERS as well. These symptoms dissappear when I re-take my dose, but then I am back on the nightmare cycle. No one told me about this, and I don\\\'t believe the drug company put out a disclaimer regarding withdrawl symptoms(anyone know about that?). I am interested in filing a class-action lawsuit against the drug manufacturer. Anyone who is interested, please contact me @ ceciliariley@aol.com. This is SERIOUS!
