"i&#039;ve had zero nausea, but zero sex drive and i have a hard time concentrating at work. i&#039;ve been taking 20 mg for about 6 weeks. i take it at bedtime. i have been very sluggish and have gained about 10 pounds. i also have terrible gas so i have to take gas pills daily.  it has helped with my depression, but my job is suffering because i cannot concentrate at all. i&#039;m thinking of asking my doctor to change my med because i will get fired soon if i keep this up! i no longer want to kill myself, but soon i will be obese, unemployed and sleepy. then i will be more depressed..."
