"the extreme sleepiness and lack of efficacy ceased like a light switch - suddenly, after a couple of weeks of sleepy torture that didn&#039;t help at all, it worked for my depression and the sleepiness was gone. i woke up one morning to find i could breath without the feeling of having my lungs filled with tar (one symptom of my depression).  i stayed on it for 2 years, and it alleviated my depression continuously while allowing me to feel like &quot;myself.&quot;  however, it did make me hungry and i gained about 15 lbs.  worth it.  when life improved, i tapered off, and have been fine ever since.  if you try it, give it a chance.  my doctor said 60% of his patients report a &quot;light switch&quot; experience with it."
