Hi, I've been on effexor xr for about a year, started at 37.5 and moved up to 112.5mg. Recently my doctor and I decided to start diminishing my dosage. We went to 75mg for about 3 weeks and now down to 37.5....this is miserable. I'm having thoughts I haven't had before, I can't focus on anything. All the normal breathing and thought stopping techniques don't seem to help. Has anyone else had these problems with Effexor? I feel like I'm going absolutely nuts.
