"i began taking this medication october 2011 for depression and anxiety as recommended by general practitioner. (it is the only medicine for depression/anxiety that i have ever taken) i ramped up weekly from 0.5 to 15 mg. my doc wanted me on 20 mg per day but i decided 15mg was for me. i felt an immediate boost upon first taking only 0.5. felt a sense of happiness that had been missing for many, many years.  at 15 mg i felt much less stressed and much happier overall. i could deal with friends, family and strangers much more easily. after a few months of doing well i noticed that the &quot;fog had set in&quot;, i had a hard time focusing on anything for an extended period. this was accompanied by increased anger and no sex drive at all. i have now weaned myself off."
