anxiety
"This drug did very well for me initially, at 10mg.  My dosage over 7 years kept increasing and now I am convinced that over time this medicine will deplete your natural serotonin levels and fails to work or not work at all.  At 10mg the side effects were not that noticeable at all, but at 20 mg the side effects were much more pronounced  Especially lethargy, increased panic attacks/anxiety, weird dreams, and sexual side effects to name just a few. Everyone is different, but for me this drug worked well at a small does for about 21/2 years, then slowly stopped working to the point where I was just having side effects from the med.  Am tapering off it and feel very well so far."
