I've been on Cymbalta since Nov 2007. I am now at the max dose of 120mg daily. I haven't noticed any weird side effects like what you have mentioned. In fact, I don't recall having any side effects at all. Every body is different and will react differently to the same medication. Cymbalta has really helped my depression, while I am also on a mood stabilizer, I am doing so much better now than I was 6 yrs ago.
