Yes, I have. I can't tolerate anti-depressants very well. I have been on (not at the same time) Zoloft, Paxil, Prozac, Wellbutrin, and some other one I can't recall. Dr now wants me to take Cymbalta and I refuse. Another Dr gave me Effexor & I wouldn't take it. Some meds just have strange side effects that go away after time, but if you've been taking it 11 weeks I would think you would have adjusted by now. Unless they recently changed your dosage, which could also cause side effects.
I have had the strange symptoms you wrote about when I wasn't on any meds, so it may just be due to your anxiety which causes all kinds of strange symptoms with me.
