Hi, Ive been on effexor xr for many years, and am now really scared to go off them, as over the yrs, Ive missed a few doses and what an awful, scarey, horrible feeling in my head and eyes. Does any one else have this feeling when they miss a dose? I may have to change this medication to another for anxiety disorder but not sure what my Dr is going to say yet. Just a bit worried about it. If any one has any other suggestions about medications for anxiety that work for you I would really appreciate it.
